摘      要：In the present work,bimetallic silver/zinc was applied into the degradation of trihalomethanes,THMs:CHCl_(3),CHBrCl_(2),CHBr_(2)Cl,and CHBr_(3).The kinetics reaction rates and removal efficiencies of the THM compound mixtures,in the aqueous solutions,were *** experiments were conducted under mild conditions,ambient temperature,and *** primary degradation reaction followed a pseudo-first-order kinetic *** first-order rate constants and the degradation efficiencies followed the decreasing order of CHBr_(3)CHBr_(2)ClCHBrCl_(2)CHCl_(3).The bond dissociation energy and hydrophilic/hydrophobic characteristics of the THM compounds may become the most important parameters affecting the degradation kinetics and efficiency by bimetallic Ag/Zn.
