以泡沫铜作为催化剂与超声波耦合降解罗丹明B溶液,分别考察了H2O2投加量、溶液初始pH以及超声功率对罗丹明B降解效果的影响.结果表明,在H2O2的投加量为5.0 mmol/L、超声功率300 W、溶液初始pH为3.0的条件下,初始质量浓度为5 mg/L的罗丹明B溶液反应25 min,去除率为99.41%,比超声单独作用相比,增加了86.75个百分点.理论分析显示,超声-泡沫铜耦合体系通过羟基自由基氧化和泡沫铜还原协同降解罗丹明B.“,”In the paper,rhodamine B (RhB) was degraded by ultrasound-assisted Fenton-like process with the foam copper as the catalyst.The influencing factors,such as initial pH,the dosage of H2O2 and ultrasound power are studied.The results manifest that the optimum conditions:initial pH=3,dosage of H2O2 5.0 mmol/L,ultrasound power 300 W,ultrasound time 25 min.Under above conditions,the degradation of RhB was 99.41%,which improved by 86.75 percentage points compared with ultrasound alone.Meanwhile,it indicates that the degradation of RhB follows the oxidation of hydroxyl radicals and the reduction of foamy copper.
