摘　　要：本文对阴离子染料吸附剂ADA—4的吸附、解吸和再生性能及机理进行了研究。实验结果表明,ADA—4吸附剂用于印染污水脱色,不但对污水中的阴离子染料有很强的吸附能力,大大降低了污水色度,而且还可以通过既简单又经济的方法使吸附剂——载体上的染料解吸,使其吸附性能再生。经反复利用10次,其吸附率下降约在3％以下。Adsorption,desorption,regenerated performance and mechanism of adsorbent ADA-4 to anionic dyes are studied in this article. The results show that ADA-4 has a strong power of adsorption to anionic dyes in effluent and can greatly decrease the colourant in effluent when it is used as a decolouring agent of dyeing and finishing effluent. The dyes adsorbed on the carrier of the adsorbent can be desorpted by a simple and economical method tana the carrier's adsorption power can be regenerated. When the adsorbent is used 10 times,its adsorbability will drop about 3%.
