CORRECTIONS Chromite Method for Determination of Inorganic Peroxides in Alkaline Solution Richard W. Lynch and Maurice R. Smith (Anal. Chem. 1980,52,1998-1999). Hydrogen peroxide weight fractions in Table I are calculated from eq 3, rather than from nonexistent eq 4 (as appear in the table). Similarly, hydrogen peroxide weight fractions in Table I1 (footnote a ) are also calculated from eq 3. The unnumbered equation at the bottom of the first column on p 1998is, in fact, eq 3. Finally, the current address of Richard W. Lynch is: Tennessee Valley Authority, 1170 Chestnut Street Tower 11, Chattanooga, TN 37401.
Graphical Techniques for Kinetic Data Analyses of Alkaline Phosphatase Jack W. Frazer and Hal R. Brand (Anal. Chem. 1980,52, 1730-1738). Equations 15 and 16 are inadvertently inverted. Equations 15, 16, and 18 should read as follows:
On p 1736 following eq 19 there is a typographical error, Le., Cs is C1 and the equations are C1 = k,[E],/Ks, C2 = I/&, and C3 = l/Ki.
