一种椰壳基活性炭的制备方法
By using a staged treatment with a composite activator of H3PO4 and ZnCl2, the pore structure of coconut shell-based activated carbon was optimized, solving the problems of high energy consumption and uneven pore size distribution in traditional methods. This resulted in activated carbon with high specific surface area and a high proportion of medium and large pores, thus improving the adsorption effect on COD in water.

Abstract
本申请涉及活性炭制备领域，公开了一种椰壳基活性炭的制备方法。该制备方法包括：原料预处理，将椰壳粉碎，过筛，洗涤，干燥，得到椰壳颗粒；活化预处理，将椰壳颗粒浸渍至活化剂中，浸渍结束后静置，沥干；碳化处理，在氮气氛围下，升温至300°C，保温碳化，得到碳化物；梯度活化处理，将碳化物在CO2氛围下，升温至500°C，保温活化，保温结束后，继续升温至750℃，保温活化，得到活化物；后处理，回收去除活化剂，干燥。本申请的方法优化了活性炭的孔隙结构，在保证高比表面积的同时，提高了中大孔比例，进一步提高了活性炭对水体COD的吸附能力，能满足工业废水、印染废水等高COD有机污染物的污水处理。
