a pHBA degradation in different systems and (b) corresponding removal rate constants; c OA degradation in Fe-NPC/O3 system; d Comparison of mass activity for catalytic ozonation in terms of OA degradation; Effects of (e) NaCl concentration (insert: corresponding kinetic rate constants) and (f) Na2SO4 concentration (insert: corresponding kinetic rate constants); g Advanced treatment of biotreated coal chemical wastewater; h COD and TOC removal after treatment; i Reusability tests of Fe-NPC. The error bars in the figures represent the standard deviations from triplicate tests.
