摘要

对于公共卫生和生态系统保护而言，废物资源的再利用仍然是一个具有挑战性的问题。以废羽绒纤维为原料成功制备了天然超细羽绒颗粒(NSDP)，并对其去除二元染料溶液中的亚甲基蓝(MB)和甲基橙(MO)染料进行了研究。通过扫描电镜(SEM)和n2吸附对吸附剂进行了表征。研究了NSDP对这两种染料的吸附行为与ph的关系。结果表明，NSDP表面的表面积为7 277 cm2 /g，具有丰富的官能团(羧基、羟基和胺基)。NSDP的吸附量对ph值有较强的依赖性。结果表明，NSDP可作为一种高效、经济的吸附剂去除纺织废水中的染料。

Super Dye Adsorption Capability of Natural Superfine Down Particles for Organic Contaminant from Binary Dye Mixture

Reuse of waste resources is still a challenging issue for public health and ecosystem protection. Herein, natural superﬁne down particles (NSDP) were successfully prepared from the wasted down ﬁbers and investigated for the removal of methylene blue (MB) and methyl orange (MO) dyes from the binary dye solution. The adsorbent was characterized by scanning electron microscopy (SEM) and N 2 adsorption. The adsorption behavior of NSDP for these two dyes was investigated as a function of pH. The results showed that the NSDP surface has surface area of 7 277 cm 2 /g and an abundance of functional groups (carboxyl, hydroxyl and amine-groups). The adsorption capacity of NSDP was strongly pH-dependence. The results indicated that NSDP can be used as an eﬃcient and economic adsorbent to remove dyes in the textile eﬄuents.
