Rapid adsorption of benzotriazole onto oxidized carbon cloth as an easily separable adsorbent.

ABSTRACT: A commercial carbon cloth (CC) was oxidized by HNO₃ acid and the features of the plain and oxidized CC were evaluated. The results of characterization illustrated that HNO₃ oxidization duplicated the oxygen-containing functional groups and the surface area of the CC. The adsorption performance of the plain and oxidized CC (Oxi-CC) toward benzotriazole (BTR) was compared. The results disclosed that the uptake of BTR by oxidized CC was greater than the plain CC. Thence, the affinity of oxidized CC toward BTR was assessed at different conditions. It was found that the adsorption was quick, occurred at pH 9 and improved by adding NaCl or CaCl₂ to the BTR solution. The kinetic and isotherm studies revealed that the surface of Oxi-CC is heterogeneous and the adso
