医用脱脂棉经氢氧化钠浸泡制成碱纤维，再用二硫化碳黄原酯化后，经水洗、干燥而制成黄原酯棉。研究了自制的黄原酯棉对铅（Ⅱ）和铜（Ⅱ）的动态吸附特性，其吸附回收效果用火焰原子吸收分光光反法进行测定检验。结果表明：在ｐＨ＝１～５的范围内，浓度为２０～５００μｇ／Ｌ的铅（Ⅱ）和铜（Ⅱ）能被定量吸附回收，回收率在９７％～１０３％之间，定量富集倍数在１００倍以上；所制黄原酯棉对铅（Ⅱ）和铜（Ⅱ）的饱和吸附量均在１ｍｇ／ｇ（ＣＣＸ）左右为宜，这既能满足一般要求，也使制品有一定强度；在用盐酸调节试液酸度和作为洗脱液时，回收率低，而用硝酸代替之时，可达到定量回收，所选洗脱液是１ｍＬ５０％（Ｖ／Ｖ）的硝酸溶液。
Medical absorbent cotton soaked by sodium hydroxide made of alkali fiber, and then carbon disulfide Huangyuan esterification, after washing, drying and made of xanthate cotton. The dynamic adsorption characteristics of lead (Ⅱ) and copper (Ⅱ) on the native xanthate were studied. The adsorption and recovery results were determined by flame atomic absorption spectrophotometry. The results showed that Pb (Ⅱ) and Cu (Ⅱ) with the concentration of 20 ~ 500μg / L could be quantitatively adsorbed and recovered with the recoveries between 97% and 103% in the range of pH = 1 ~ Times the number of times more than 100 times; the xanthate cotton yttrium (Ⅱ) and copper (Ⅱ) saturated adsorption capacity of about 1mg / g (CCX) is appropriate, both to meet the general requirements, but also make a certain product Strength; when hydrochloric acid is used to adjust the acidity of the test solution and as the eluent, the recovery rate is low, and when it is replaced by nitric acid, quantitative recovery can be achieved. The selected eluent is 1 mL of 50% (v / v) nitric acid solution.
