Study of Methylene Blue Adsorption using Activated Carbon Prepared of Green Tea

The adsorption efficiency of methylene blue(MB) in different conditions by means of ZnCl2 solution activation activated carbon of green tea was discussed.The results showed that the adsorption efficiency of MB achieved 97.42% by using activated carbon of green tea under the conditions of adsorption time 30min,activated carbon dosing quantity 50mg,volume of sample 50 mL and concentration 40 mg/L.
