摘要

为解决钢厂含铬废水的处理问题,采用超声波联合传统铁氧体法处理钢厂含铬废水,并从中回收了具有一定经济价值的铬-铁氧体产品。借助于XRD分析了产物的晶体结构,研究了硫酸亚铁和双氧水添加量、反应时间、超声波功率及pH对铬-铁氧体形成的影响,并对产物铬-铁氧体进行SEM分析和能谱分析。结果表明,当n(Fe2+)∶n(Cr6+)=7∶1、添加1.0 mL的3%H2O2、反应时间为30 min、超声波功率为40 W及调节pH=10时,能得到晶型较好的铬-铁氧体。铬-铁氧体颗粒为纳米级,其铁、铬、氧含量基本符合亚铬酸亚铁(FeCr2O4)中各元素含量要求。

Abstract

:In order to solve the problem of treatment of chromium-containing wastewater from steel plant,the ultrasonic com-bined with traditional ferrite method was used to treat the chromium-containing wastewater from steel plant,and the chromium-ferrite products with certain economic value were recovered.The crystal structure of the products was analyzed by XRD.The effects of the content of ferrous sulfate and hydrogen peroxide,reaction time,sonication power and pH on the formation of chromium-ferrite were studied.The chromium-ferrite was examined by SEM and analyzed by energy spectrum.The results showed that whenn(Fe2+)∶n(Cr6+)=7∶1,adding 1.0 mL 3% H2O2,reaction time was 30 min,sonication power was 40 W and adjusting pH=10,the chromium-ferrite with good crystal form could be obtained.The chromium ferrite particles were nano-scale,and the contents of iron,chromium and oxygen basically met the requirements of each element content in ferrous chromite(FeCr2O4).
