RSBCCuO活化PDS氧化降解苯胺的研究
摘 要
苯胺是一种广泛应用于工业、农业生产的胺类物质，但是同时苯胺毒性很强，是一种危害环境及人体健康的重要污染物。因此，开发绿色环保，经济有效的方法处理苯胺废水已成为当务之急。本实验通过水热法合成制备水稻桔杆生物炭负载氧化铜(RSBCCuO)，并以此作为催化剂活化过二硫酸盐(PDS)来氧化降解苯胺，并通过对比试验研究在不同反应体系中苯胺的降解效率，具体包括RSBC/PDS体系、CuO/PDS体系和RSBCCuO/PDS体系。通过改变苯胺初始浓度，初始pH值，RSBCCuO催化剂用量，PDS浓度等条件探索苯胺降解的最佳条件，推测可能的反应机理。实验结果表明，在温度为25 ℃，苯胺初始浓度为10 mg/L，RSBCCuO用量为0.4 g/L，PDS浓度为50 mg/L，初始pH为6.0时，15 min内苯胺几乎可以降解完全，因此可以说明RSBCCuO催化过二硫酸盐可以有效降解苯胺。通过在反应体系中加入超氧根自由基抑制剂对苯醌(BQ)及单线态氧抑制剂糠醇(FFA)，由实验结果可推测在降解苯胺过程 *51今日免费论文网|www.51jrft.com +Q: ^351916072#

OXIDATIVE DEGRADATION OF ANILINE BY PEROXYDISULFATE ACTIVATED WITH RICE STRAW BIOCHAR MODIFIED BY COPPER OXIDE
ABSTRACT
Aniline is one of the amines widely used in industries and agricultures. Nevertheless, aniline is a significant pollutant frequently detected in environment. It is urgent to develop efficient and environmental friendly approaches for disposing the wastewater containing aniline. In this study, rice straw biochar loaded copper oxide (RSBCCuO) was prepared by hydrothermal method as a catalyst for PDS activation to degrade aniline. The impacting factors including initial concentration of aniline, initial pH, catalyst dosage, PDS concentration conditions on the degradation of aniline were investigated to determine the optimal experimental conditions for the removal of aniline. The results showed that aniline could be completely degraded within 15 min at the temperature = 25 ℃, the initial concentration of aniline = 10 mg/L, RSBCCuO dosage = 0.4 g/L, PDS concentration = 50 mg/L, and the initial pH = 6.0. Thus, it can be concluded that PDS catalyzed by RSBCCuO can effectively decompose aniline. By adding superoxide radical inhibitor of benzoquinone (BQ) and singlet oxygen radical inhibitor of furfuryl alcohol (FFA) into the reaction system, the degradation of aniline was greatly suppressed, which suggests that superoxide radical and singlet oxygen played a major role in the degradation of aniline.This study provides us a novel and promising catalyst for PDS activation to treat wasterwater containing aniline and its derivation.
