查询词典 unpurified

It is shown that polystyrene has been grafted on the surface of nmSiO2 particles and the grafting ratio is about 40%. The surface of nmSiO2 could be treated effectively by KH570in absolute ethanol at 25℃, 48h. The nmSiO2-g-PSt unpurified by toluene appear microsphere in which nmSiO2 particles are contained, whereas the purified one appear internet formed by many pieces. The grafting ratio of PSt on nmSiO2 surface could be influenced obviously by dispersion agents content and agitation speed, whereas the morphology of nmSiO2-g-PSt purified is rarely changed.

结果表明：常温下在无水乙醇介质中处理48h以上可获得良好的硅烷处理效果；PSt已接枝包覆于nmSiO2表面，接枝率约40%；经甲苯洗涤前nmSiO2-g-PSt呈多粒子包覆微球状，洗涤后呈单粒子包覆网状结构；分散剂用量、搅拌速度改变对接枝率有影响，但对包覆形态影响不大。

The optimal medium consisted of 2% glucose, l.5% soluble starch, 2% peptone, 0.5% soya powder, 2.5% unpurified salt, initial pH 6.0~6.5. The optimum culture conditions was: 5% inoculation amount, seed cultural time 24h, 150mL liquid medium in 500mL Erlenmeyer flask, 29℃ and 180r/min for 3d.
