新型吸附剂的制备及其对亚甲基蓝染料吸附行为的研究

Study on a New Absorbent and Its Absorption Behavior on Methylene Blue Dyes

以一种粘土为材料研究制备一种新型吸附剂,并用其对染料模拟用水进行吸 附脱色处理．研究表明:在10％HCl,改性温度60-70℃、改性处理时间48h、粘土粒径 0．017mm条件下制备的吸附剂,当pH=9、投加量0．1 g／L、静置时间36h、染料用水色度 低于15mg/L时,色度去除率达97％以上．

This thesis mainly studies and prepares a kind of new-type absorbent and it in application dealing with the dyestuffs water while decolouring.Experimental study indicates that better condition is to prepare to modify in the craft： HCl density 10%, modify 60 -70 of temperature, modify and punish time 48h, eye of foot-path 900 of clay; Better condition of dealing with waste water is： pH =9.0, throw it with measuring 0.1 g/L, put time 36h quietly, mixes speed 200-300r/min,the density of the waste water is lower than 15mg/L, the getting rid of rate of colour is more than 97%.
