摘要
用去除鳞片层的废弃羊毛作为六价铬的吸附剂,利用单因素法,考查溶液的pH、吸附温度、吸附时间等对吸附效果的影响,确定了铬(VI)的最佳吸附工艺,即溶液pH=2,吸附温度30℃,吸附时间90 min。再生循环研究表明,经过3次循环以后,废弃羊毛仍具有一定的吸附能力。与其他吸附材料比较,废弃羊毛具有较高的吸附量。
The stripped scale waste wool was used as adsorbent for chromium (Ⅵ) ions. The influences of the solution pH value, adsorption temperature and adsorption time on adsorption effect were investigated by the single factor method. The optimal adsorption process of chromium (Ⅵ) ions was determined as follow: the solution pH value of 2, adsorption temperature of 30℃ and adsorption time of 90 rain. Recycling investigation demonstrated that the waste wool still showed a certain adsorption capacity after three cycles. Compared with other absorbent material, the waste wool presented a higher adsorption capacity.
