石棉摩擦材料废弃物制吸附剂对染料的吸附研究

Study on a Dye Adsorption Made from Waste Asbestos Friction Materials.

以石棉摩擦材料加工废弃物为材料制得的吸附剂，在色度５００００倍的溶液中对阳离子黄Ｘ－５ＧＬ的静态吸附量为１５９．６８ｍｇ／ｇ；在色度５０００倍的溶液中对阳离子艳蓝ＲＬ的静态吸附量为７９．６８ｍｇ／ｇ；对毛纺厂腈纶染缸废水的处理量可达２８０ｍｌ／ｇ；对活性染料亦有较好的吸附效果．吸附饱和后的吸附剂可通过后处理实现资源化．

A kind of new adsorbent was made from waste asbestos friction materials.The static adsorption capacity for cation yellow X 5GL is 159 68mg/g in its aqucous solution which chromaticity is 50000,and the adsorption capacity for cation blue RL is 79 68mg/g in its solution which chromaticity is 5000.The treating amount for waste water generated in the dyeing process from woolen textile factory can be as high as 280ml/g.This adsorbent can also effectively adsorb reactive dye,and can be easily regenerated through aftertreatment when saturated adsorption is reached.
