摘要
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%.
