Correction to New Calix[4]arene Appended Amberlite XAD‑4 Resin with Versatile Perchlorate Removal Efficiency Shahabuddin Memon,* Asif Ali Bhatti, and Najma Memon J. Chem. Eng. Data 2013, 58 (10), 2819−2827. DOI: 10.1021/je400554q

he pseudo second order kinetic equation in linear form (eq 8) in the original article was published as:

⎛ ⎞ t t ⎟ ⎛⎜ 1 ⎞⎟ = ⎜⎜ +⎜ ⎟ 2⎟ qt ⎝ k 2qe ⎠ ⎝ qe ⎠

This should be changed as follows: ⎛ ⎞ t 1 ⎟ ⎛⎜ 1 ⎞⎟ = ⎜⎜ + ⎜ ⎟t 2⎟ qt ⎝ k 2qe ⎠ ⎝ qe ⎠

Also, reference 41 is not the proper reference for pseudo second order kinetic equation (eq 8). This should be removed and changed to: Ho, Y. S.; McKay, G. Pseudo-second order model for sorption processes. Process Biochem. 1999, 34 (5), 451−456.
