摘　　要：本文采用氧化还原法对高岭土去铁增白,考察了白度与原浆浓度、保险粉用量、p H值等因素的依赖关系。研究表明:控制原浆浓度为10%、保险粉的质量比5%及p H=3时,高岭土的白度从26.2%提高到了78.6%。In the paper, aredox method was used to remove iron for the whitening of Kaolin. The whiteness of Kaolin depends on the concentration of protoplasm,the mass ratio of sodium hydrosulfite and pH values of solution, etc. the result showed that the whiteness of Kaolin would be improved from 26.2% to 78.6 when the concentration of protoplasm, the mass ratio of sodium hydrosulfite were controlled at 10% and 5% ,respectively,in pH =3 solution.
