摘要
针对部分皮革样品易掉色的问题,研究了活性炭对染料和甲醛的分离效果,结果表明:活性炭对染料具有很强的吸附能力,且对甲醛具有反应惰性;经活性炭吸附处理,加标样甲醛的回收率为97%以上,染料脱除率90%以上,活性炭吸附可消除洗脱染料对游离甲醛含量测定的干扰。
Aimed at the problem of fading in some leather samples, the separating effect of dyes and formaldehyde was studied by activated carbon adsorption method. The results show that activated carbon have a strong adsorption capacity on dyes, but reac- tionlessness on formaldehyde. After activated carbon adsorption treatment, the recovery of formaldehyde is more than 97%, and the removal rate of dyes is more than 90%. The activated carbon adsorption method can effectively eliminate the interference of dyes on determination of free formaldehyde content.
