摘要
Abstract
The purification of halloysite in Iincang of Yunnan province was studied with dispersion and centrifugalization process, and high purity halloysite nanotubes was prepared. The study was carried out on influences of solids content, centrifugal speed, the type and dosage of dispersant on the purification efficiency. The results showed that the optimum conditions were centrifugal speed 1000 r/min, solids content 20% and PAANa 0.1%. Under the optimum conditions, the purity of the products reached more than 90% purity and the yield rate was more than 30% , and the halloysite kept the nano - metre hollow tubular structure.关键词
