摘要
对钛白粉生产中的副产物硫酸亚铁进行综合利用 ,以微生物为催化剂 ,在常温常压下用空气为氧化剂氧化硫酸亚铁 ,经水解、聚合反应生成聚合铁。制得的聚合铁酸度低 ,盐基度高 。
An overall use of ferrous sulfate during the production of titan white was conducted;and polyferric sulfate is produced using microorganism as a catalyst,then oxidizing ferrous sulfate by air at normal temperature and pressure,as well as through hydrolysis and polyreaction,the polyferric sulfate has low acidity and high base index, which possesses a unique effectiveness of treating low temperature water with a low turbidity.
