摘要：

The process of hydrogen peroxide triggered by zero-valent copper (Cu 0 /H 2 O 2 ) was usually used to decompose organic pollutants. Nevertheless, its oxidation efficacy was restricted by the disproportionation of Cu⁺ along with the interaction between Cu⁺ and O₂. The research found that the combination of chloride ion (Cl − ) and hydroxylamine (HA) obviously enhanced the Cu 0 /H 2 O 2 process, and 87.1% of tetracycline was degraded in 15 min. In the HA/Cl − /Cu 0 /H 2 O 2 process, on the one hand, the cycle of Cu 2+ /Cu + was persistently ...
