| 摘 要： | 作为生物大分子吸附剂,黄原胶具有吸附重金属离子的结构优势。该文主要研究了黄原胶对常见重金属Pb2+的吸附性能,并重点考察了吸附时间、溶液pH值2、温度、黄原胶浓度对吸附性能的影响。研究结果表明:吸附时间取30 min为宜;溶液的pH值在6.8~8.5之间时,黄原胶对Pb2+的去除率较高;适宜的吸附Pb2+温度为35℃;适宜的黄原胶用量为0.8 g/L。在此条件下,黄原胶对Pb2+的去除率达到80%以上。

| Abstract: | As a kind of biological adsorbent,the structure of xanthan gum has the advantage of adsorbing heavy metal ions.This paper mainly studies the adsorption of the common heavy mental ion Pb2+ on xanthan gum,and the factors that influence the adsorption capacity such as adsorption time,pH,temperature,Xanthan gum concentration are investigated.Results show that the suitable adsorption time is 30 min,the adsorption efficiency is maximum as the pH is between 6.8~8.5,the suitable adsorption temperature is 35 ℃and the appropriate xanthan gum concentration is 0.8 g/L.Under these appropriate conditions the removing rate of Pb2+ is above 80%. |
