摘要
将煤渣改性 ,测定其比表面积 ,再在NaCl溶液中测定其等电点 ,最后用对苯二酚对其吸附特性进行表征。结果表明 ,制得的改性煤渣在接近中性时 。
After modified cinder,its specific surface is tested for 10.8m 2/g. In Nacl solution, its isoelectric points are tested for 6.8. At last, its adsorption is characterized with P-dihydroxy -benzene. The result show that this cinder has beffer ability of absorption to P-dihydroxy-benzene when it approaches neutral, and the pattern of absorption meets the langmuir isothermal equation.
