以膨胀珍珠岩收尘粉、沸石、膨润土和凝灰岩等非金属矿为主要原料，采用高温快烧的方法制备出一种轻质复合陶粒。采用扫描电子显微镜和全自动吸附仪研究了样品的形貌和比表面积。结果表明，陶粒烧成的最佳工艺条件为：焙烧温度850℃、焙烧时间10 min。以罗丹明B为模型污染物考察了陶粒样品的吸附性能，2 g样品对20 mL质量浓度为40 mg/L的罗丹明B溶液去除率达到93.1%。陶粒滤料15次重复使用后的去除率为87.7%。
以膨脹珍珠巖收塵粉、沸石、膨潤土和凝灰巖等非金屬礦為主要原料，採用高溫快燒的方法製備齣一種輕質複閤陶粒。採用掃描電子顯微鏡和全自動吸附儀研究瞭樣品的形貌和比錶麵積。結果錶明，陶粒燒成的最佳工藝條件為：焙燒溫度850℃、焙燒時間10 min。以囉丹明B為模型汙染物攷察瞭陶粒樣品的吸附性能，2 g樣品對20 mL質量濃度為40 mg/L的囉丹明B溶液去除率達到93.1%。陶粒濾料15次重複使用後的去除率為87.7%。

A lightweight composite ceramsite was prepared by high temperature fast burning using some non-metallic minerals such as perlite dust power, natural zeolite, bentonite and tuff. Morphology and speciifc area of samples were characterized by scanning electron microscope (SEM) and surface and aperture meter. The optimal technological conditions were investigated as calcination temperature 850℃and calcinations time 10 min. Performance of adsorption was evaluated by employing rhodamine B as a model of pollutant. 93.1%of 20 mL 40 mg/L rhodamine B was removed over 2 g ceramsite. 87.7%of rhodamine B could be removed after recycling 15 times.
