凹凸棒石颗粒吸附剂制备及其性能

Preparation and Property of Attapulgite Granulated Absorbent

在凹凸棒石黏土中加入低熔点烧结剂,制备了凹凸棒石颗粒吸附剂。实验表明,在600℃下煅烧20min,该颗粒吸附剂具有较低的散失率和良好的吸附性能。颗粒吸附剂对有机染料阳离子红的吸附等温线属于Langmuir型。

By mixing the attapulgite clay and the low-meltlng point agglomerant, tha attapulgite granulated absorbent is prepared. The results of experiment indicate that the granulated absorbent is possessed of low-loss ratio and fine absorptivity for Cation Red dye after calcination at 600℃ for 20 min. The granulated absorbent has Langmuir Absorption Isotherm.
