摘　　要：采用等离子体技术对废乳胶进行预处理,利用鞘氨醇单胞菌对其进行脱硫,考察等离子体预处理前后废乳胶亲水性的变化,研究等离子体预处理对废乳胶脱硫效果的影响。结果表明:经等离子体预处理后,废乳胶表面亲水性明显改善;与直接脱硫的废乳胶相比,等离子体预处理后再脱硫的废乳胶表面的砜类基团明显增多,硫质量分数减小,氧质量分数显著增大,硫-氧键含量明显增大,且交联密度明显降低;等离子体预处理能够有效促进废乳胶的微生物脱硫,明显改善脱硫效果。Waste latex rubber（WLR）was treated with plasma technology and desulfurized by sphingomonas,the hydrophilic property of WLR before and after treating with plasma technology was investigated,and the effect of plasma treatment on the desulfurization of WLR was studied. The results showed that,WLR after plasma treatment（Plasma-WLR）had better hydrophilic property. Compared with desulfurized WLR（DWLR）,the content of sulfone groups on the surface of desulfurized plasma-WLR（plasma-DWLR）was increased,the mass fraction of sulfur was decreased,the mass fraction of oxygen was increased,the amount of S—O bonds was increased obviously,and the crosslink density of plasma-DWLR was lowered obviously. Plasma pretreatment could effectively facilitate the microbial desulfurization of waste latex.
