蔗渣纤维素黄原酸酯的制备及稳定性研究

以甘蔗渣为原材料,于20％(wt)的NaOH溶液中碱化24 h,在碱性条件下加入用量为0.5 mL/g的CS2,在30℃反应2.5 h,合成了蔗渣纤维素黄原酸酯(BCX)；并对其合成条件进行了优化,对其处理重金属离子的效果进行了评价.研究结果表明,BCX对重金属废水中的Ni2+、Cu2+、Zn2+、pb2+的去除率均在...

Synthesis and Stability of the Bagasse Cellulose Xanthate

The synthesis process of bagasse cellulose xanthate(BCX) is that:the bagasse was put into 20% concentration of NaOH solution,soaked 24 h,filtered,then it was set into the alkaline solution,added 0.5 mL/g CS2 slowly,Stirred 2.5 hours under 30 degrees;the author optimized the BCX on the synthesis conditions and evaluated the effect of adsorption of heavy metal ions.The results show that,BCX have good adsorption on the removal of nickel ions,Copper ions,zinc ions,lead ions in waste water,the removal rate can reach more than 96%;the pH and concentration of the treated wastewater which from Jiangmen another electroplating factory can reach the national emission standards;Residue of metal ions adsorbed has better stability in the neutral water environment,the metal ion release very little.
