| 摘 要： | 研究了利用天然高分子聚合物壳聚糖与Ｃｕ（Ⅱ）的配合物配位吸附尿素的方法。结果表明：当配合物中含铜质量分数为６．５％，溶液ｐＨ＝６．０时吸附尿素效果最好。当尿素原液质量浓度为１３００．０ｍｇ／Ｌ，吸附时间８．０ｈ时，吸附量可达８３．６ｍｇ／ｇ。

| Abstract: | A method for
adsorption of urea with chitosanCu() complex was reported. When the original concentration of
urea solution was 1 300.0 mg/L, the sorption capacity of this complex for urea was about 83.6
mg/g under the optimal conditions:the Cu() content was 6.5% in chitosan-Cu() complex, the
adsorption time was 8.0 h and pH=6.0. |
