1·The results show that the purification and the heat treating can not improve the hygroscopic property of attapulgite effectively.
研究结果表明：提纯和热处理并不能有效的改善凹凸棒石粘土的吸湿性能。
2·The decolorizing capability of PRHA for soybeans crude oil was 3 times as much as that of activated attapulgite commonly used in vegetable oil industry.
PRHA 对中性大豆毛油的脱色能力是目前植物油工业中常用的活性凹凸棒石粘土的3倍。
1·There are many species and types of plastic clay in China. According to their mineral compositions, they are divided into Kaolinitic clay, Montmorillonite clay, Sepiolite clay and Attapulgite clay.
我国塑性粘土种类繁多，按矿物成分可分为高岭石质粘土、蒙脱石粘土、海泡石粘土、凹凸棒石粘土等。
2·CONCLUSION: Acidified attapulgite could be used as adsorptive clarifier in decoction of Radix et Rhizoma Notoginseng and composite Dansen pill.
结论：酸化凹凸棒石可作为三七药材和复方丹参滴丸水煎提取液的吸附澄清剂。
1·The removal effect of ammonia nitrogen and organic material with composite attapulgite filter by static adsorption experiment and dynamic filtration experiment was studied.
通过静态吸附实验和动态过滤实验研究复合凹凸棒滤料对氨氮和有机物的去除效果。
