Experimental Study of Adsorption of Cu~(2+) of Pure Palygorskite
The experiment has been done to investigate the adsorption of Cu~(2+) of palygorskite based on purification of palygorskite clay ,the result indicates that the adsorption is mainly affected by such factors as vibrating rate , adsorption time,aqueous pH, and the adsorption curve(30℃) of Cu~(2+) on palygorskite confirms with Langmuir equation or BET equation . In this study, the optimized technological conditions are vibrating rate 150 r·min~(-1), adsorption time 60 min , and pH5.2.The corresponding removal efficiency of Cu~(2+) is 100%。
