利用钛白副产物绿矾制备纳米α-FeOOH的研究
- A study on preparation of nanometer α FeOOH particles by ferrous sulfate of by-product
- 摘要:以硫酸法钛白副产物绿矾为原料,制备纳米α-FeOOH.研究净化过程中水解温度、水解时间、还原剂等对绿矾净化效果的影响;采用酸法制备纳米αFeOOH,所得粒子用DTA、TEM和XRD等手段进行表征,结果表明粒子为α-FeOOH,颗粒长约80nm、宽约20nm.
- Abstract:Nanometer α FeOOH particles were prepared by purified ferrous sulfate of by-product in acidic medium.The hydrolyzing temperature, hydrolyzing time and reductant Fe powders were studied.The prepared particles were characterized by the measurement of TEM, DTA and X-ray.
