| Abstract: |
| 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. |
