Effects of chloride ion on degradation of Acid Orange 7 by sulfate radical-based advanced oxidation process

摘要

@@ 1. Introduction Sulfate radical (SO4*, E0=2.5-3.1 V) based on cobalt/peroxymonosulfate (Co/PMS) system may react selectively via electron transfer with organics over a wide pH range (2-8), and completely destroy the pollutants in wastewater[1].
