Abstract

One of the equations that used in this article Eq. (4) was applied incorrectly. The correct form of the equation is as below:lnqeq-q=lnqeq-K1t Also, the K1 (1/min) value reported in Table 2 was incorrect. The correct value of K1 (1/min) is 0.0131. The authors would appreciate from Dr. Yuan-dong Huang who detected this error. Moreover, the authors rechecked precisely the article and presented the following corrections: – Page 250, left column: The sentence below Eq. (3) was corrected as “Where, qe is the milligram of AMX adsorbed on grams of adsorbent at equilibrium condition, C0 and Ce are the initial and equilibrium concentrations of AMX after adsorption, in mg/L, respectively.”– Page 254, left column, the second sentence below Eq. (7): the correct description of the RL parameter is as “For optimal adsorption 0 < RL < 1…”The authors would like to apologize to readers of this article because of inconvenience occurred. © 2018 Elsevier B.V.
