Fe-NS/BC@SACs+PMS体系降解水中苯胺的效能与机理
Gongye shui chuli为解决生物炭（BC）催化过一硫酸盐（PMS）高级氧化技术存在的催化效率受限、体系稳定性差、制备工艺复杂等不足，以虾壳为碳源，采用一锅热解法制备了氮、硫共掺杂锚定铁单原子生物炭催化剂（Fe-NS/BC@SACs），并构建了Fe-NS/BC@SACs+PMS体系用于降解苯胺。考察了该体系对苯胺的降解效能，包括影响因素（初始pH、催化剂投加量、PMS投加量、污染物浓度）、体系稳定性、出水生物毒性控制及污染物矿化效果等；在此基础上，进一步鉴定了反应中间产物和活性物质，提出了降解路径并揭示了反应机理。结果表明 ...
