《One-step preparation of polyimide-inlaid amine-rich porous organic block copolymer for efficient removal of chlorophenols from aqueous solution》
River water contains various inorganic and organic pollutants such as heavy metal ions,dyes,phenols,etc.In the natural adsorption process of a target contaminant,these pollutants compete with the adsorbate,which may reduce the adsorption capacity(Fukuhara et al.,2006;Nam et al.,2014).The capacities of 2,4-DCP adsorption by ARPOP and PI-b-ARPOP in river water are plotted in Fig.10a,and the linear fitting curves and parameters of the Langmuir model are shown in Fig.10b.Compared with the results of adsorption experiments in ultra-pure water(Fig.8 and Table 4),the adsorption amounts in river water were slightly lowered.In detail,the qmaxvalues for MA/TA(4/4),MA/TA/PMDA(4/3/1),MA/TA/PMDA(4/2/2)and MA/TA/PMDA(4/1/3)decreased from 188.70 mg/g240.96 mg/g,282.49 mg/g and 220.26 mg/g to 185.19 mg/g234.74 mg/g,277.78 mg/g and 213.68 mg/g,respectively.This implied that the micropollutants in river water partly competed with 2,4-DCP in the adsorption process.Hence the results show that PI-b-ARPOP can be successfully applied in the practical treatment of chlorophenols in natural wastewater.
