SOLID FUELS This section covers methods of sampling, analyzing, and testing coal, coke, and related materials. Energy Research Abstracts and Chemical Abstracts were used as the primary reference iiources. In most categories the volume of material available made it necessary to limit the number of publications in the reviiew.

Ash. Konovalov and Lukina (17A) related the errors associated with the gravimetric determination of ash in highsulfur coals. Neutron activation analysis was used by Starchik and Ryashchikov (29A) to determine carbon-oxygen ratios for calculating ash content. Janczyszyn and Aleksander (13A) used fast neutrons from a Pu/Be source to analyze pit coal for ash content. Radiometric analysis of brown coal for ash content was described by Bortnik (2A). Starchik et al. (30A) developed a procedure for optimizing a radioisotopic ash content monitor for a coal stream. Onishchenko and Belonozhko (21A)studied the effect of various parameters on ash analysis by radiometry. Page and Fox (23A) exposed powdered coal to primary radiation (46 keV and 9-16 keV y- and X-rays from zlOPb) for ash content determination. Watt and Gravitis (32A) measured the intensity of X-rays or low-energy y-rays to determine the concentration of ash.

Ash content of coal was determined by Kawatra (16A)in an aqueous slurry by measuring scattered Ag K radiation. Correction for the variation of percent solids and the iron content was necessary. Rapid estimation of percent ash in coal from percent silicon obtained vl'a fast NAA, X-ray fluorescence (XRF), and slurry injection atomic absorption spectrometry techniques (AAS) was presented by Hicks (1IA) and O'Reilly (12A). Volatile Matter. Niac et al. (19A)developed a correlation between the volatile matter and ash content of coal. The correlation coefficient is >0.99. Determination of volatile matter in coal by the diffusionreflection method was performed by Sumitomo (31A). Calculating the ratio of the intensities of the 3000-3100 cm-l and the 2870-2970 cm-l absorption bands in the infrared spectra made the method suitable for automated quality control. Procedures for the determination of volatile matter emitted from dispersed organic matter durin the analysis of pyritecontaining concentrates by thermal ecomposition were put forth by Bogorodskaya (3A). Rosenvold et al. (24A)compared differential scanning calorimetry (DSC) and nonisothermal thermogravimetry (TG) in relation to volatile matter content of coals previously analyzed by ASTM standard methods. Reliability and agreement of values for each method were discussed. Solomon (26A) studied the relation between carbon concentration and proximate analysis fixed carbon. Good agreement was obtained between measured proximate analysis values for fixed carbon and the predictions of a thermal decomposition model.

NHS generated was determined by conventional titration techniques. Waanders et al. (30B)evaluated procedures for determiningnitrogen in lignites. He found that digestion with concentrated HzS04in the presence of a catalyst (e.g., K2S04+ Vz05+ powdered Se) to convert the nitrogen to NH4S04,followed by distillation for 30 min in an alkaline solution and titration of the released NH3 was the most accurate and was applicable to brown coals. Oxygen. The concentration of oxygen in coal and fly ash was determined by Khalil et al. (12B)using 14-MeV instrumental NAA techniques. Preanalysis sample handling and selection of calibration standards were discussed. Sulfur. Baliza et al.

The gases containing SO2 and SO3 were bubbled through a solution of H20zto form H2S04,which was determined by using Ba(C104)2in 1:l acetone. Automatic coulometry was used by Popov et al. (18B)to determine total sulfur in coal. Ignition of 1300 O F in oxygen of a 50-mg coal sample produced SO2, which was absorbed in an aqueous solution of BaCl,, HC1, and HzOz, The amount of SO2 absorbed is then determined by coulometry.

Tarjan (6C) calculated calorific value of lignites based on their ash contents. Mason and Gandhi ( 5 0 developed a new five-term formula for calculating the heating value of coal from its C, H, S, and ash content.

A. INTRODUCTION This review covers a period from approximately 1978 through 1982. Earlier references are included in some cases to give a more complete picture of the technique being discussed. There has been an exponential growth in industrial hygiene over the period, and no attempt was made to cover the entire field of industrial hygiene or even the analytical aspects of industrial hygiene chemistry. For some chemicals which have come under close scrutiny, such as vinyl chloride, benzene, acrylonitrile, and formaldehyde, there are many dozens of references in the literature and anyone interested in a complete survey for a specific chemical would best be served by running a specific literature search. The intent of this review was to cover some basic concepts of the most widely used technique in personal monitoring. One in-depth review for a class of compounds, the diisocyanates, is given since, in addition to showing a multidirectional analytical approach, it may give a sense of appreciation for the degree of effort expended in the development of methods for trace amounts of reactive chemicals. To ensure a safe working environment in the laboratory and production plants, it is often necessary to determine trace 40 R

quantities of organic chemicals in the work atmosphere. For a successful program it is necessary to have good communication between the toxicologist who must assess the toxicity of the compound, the industrial hygienist who must investigate the hazard of exposure to personnel, and the analytical chemist who must determine the concentration of the compound in the environment and in biological samples for metabolism and pharmacokinetic studies. The factors which affect the collection and determination of trace quantities can be quite complex, and each specialist involved in method development, sampling, or analytical measurements must have a basic understanding of the total effort. It is beyond the scope of this review to discuss the complexities of toxicological, industrial hygiene, or analytical techniques. The main emphasis will be on collection with solid sorbents, either using ump and tube or diffusional sampling techniques, followed \y thermal desorption or solvent desorption. This includes a majority of the samples presently being collected and new methods being developed. Solid sorbent sampling tubes and dosimeters are convenient to use, can concentrate trace contaminants, and can be used for area samples as well as for employee breathing-zone samples. 0 1983 American
