PP/PEW纤维对苯系物的吸附研究

Study on BTEX adsorption by blended fiber of PP/PEW

用熔融法制备聚丙烯（PP）／聚乙烯蜡（PEW）共混物，并在一定的纺丝条件下制备PP／PEW纤维吸附材料，讨论了PEW含量对苯系物（苯、甲苯、二甲苯）吸附倍率的影响。结果表明：在PEW含量为PP的10％时，PP／PEW纤维对纯苯系物、水面苯系物的吸附倍率最大，增加量分别为31．8％～41．8％，33．3％～40．2％；对水中苯系物吸附倍率随着PEW含量增加而增大，最终是PP纤维的3倍左右。

Blend of polypropylene/polyethylene wax （ PP/PEW） were prepared using melting method, and PP / PEW fiber adsorbent materials were prepared in certain spinning conditions. The influence of PEW content on BTEX（ben- zene, toluene and xylene） adsorption ratio was stuied. The result showed that PP/PEW fiber had a maximum adsorption ratio to pure BTEX and floating BTEX on water when 10% PEW was added, the adsorption ratio had been increased 31.8%-41.8% and 33.3%-40.2%. The adsorption ratio to BTEX in water was increased apparently after introducing PEW, which was 3 times adsorption ratio of PP fiber.
