Optimization of Preparation of Hazelnut Shell Activated Carbon and Characterization
摘要
Abstract
The preparation of activated carbon of hazelnut shell and characterization were studied. Activated carbon was prepared from waste hazelnut shell through phosphoric acid activation. To optimize the preparation process of phosphoric acid concentration, activation temperature, activation time and solid-to-liquid ratio, the response surface methodology was adopted on the basis of single factor experiment. The results showed that the optimum conditions were determined as follows: phosphoric acid concentration of 48.5%, activation temperature of 494℃, activation time of 117min and solid to liquid ratio of 1:2. Under these conditions, the iodine value of activated carbon was 1029 mg•g-1. The surface characteristics of activated carbon were examined by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR) and BET specific surface area analyzer etc. The specific surface area was 1364.00m2•g-1,the average pore size was 3.17nm, and the total pore volume was 1.08cm3•g-1. Activated carbon of hazelnut shell has good adsorption effect, can be used as a kind of environmental friendly low-cost adsorbent.关键词
