Preparation of Pruning Mulberry Shoot-Based Activated Carbon by ZnCl₂ Activation

Abstract:

This paper reports the preparation of activated carbon from a new type of agricultural biomass materials, pruning mulberry shoot, by ZnCl₂ activation. The experiments in this study vary the parameters of ZnCl₂ activation procedures, such as concentration and impregnation ratio of the activating agent, temperature and time of chemical activation. The experimental results indicated that with a ZnCl₂ concentration of 50%, an impregnation ratio of 2:1, an activation temperature of 850 °C, and an activation time of 90 min, the activated carbon with better iodine and MB adsorption capacity were 1422.40 mg/g and 163.54mg/g, respectively. Therefore, the optimal preparation process of activated carbon from pruning mulberry shoot was successfully achieved by using single-factor method in this study, which can be used as adsorbents for various environmental applications.
