摘要 在实验室条件下,采用振荡平衡法研究磺胺间甲氧嘧啶(SMM)在土壤中的吸附行为,以及尿素、阴离子表面活性剂十二烷基苯磺酸钠(SDBS)、阳离子表面活性剂十六烷基三甲基溴化铵(CTMAB)和腐殖酸(HA)对吸附的影响。结果表明,SMM在土壤中的吸附分配系数Kd为18.9 mL.g-1,有机碳吸附常数KOC为466.2 mL.g-1,具有一定的移动性。50 mg.L-1尿素和阴离子表面活性剂SDBS可降低土壤对磺胺间甲氧嘧啶的吸附量,增大其在土壤中的移动性;500 mg.L-1尿素、阳离子表面活性剂CTMAB和腐殖酸(HA)也可增大SMM在土壤中的吸附。 Sulfamonomethoxine is a veterinary antibiotic drug, which can be absorbed by soil. The adsorption behav- ior of sulfamonomethoxine in soil and influence of nitrate, urea, anionic surfactant dodeeylbenzene sulfonate ( SD- BS), cationic surfaetant hexadecyltrimethyl-ammonium bromide (CTMAB) and humie acid (HA) on it were stud- ied. The results showed that: the distribution coefficient Ka of suffamonomethoxine in the soil was 18.9 mL· g^-1, or- ganic carbon distribution constant Koc was 466. 2 mL· g^-1 ; furthermore, sulfamonomethoxine possessed the mobility in the soil. 50 mL· g^-1 urea and anionic surfactant SDBS can decrease adsorption of sulfamonomethoxine in soil, in- creasing its mobility in soil. 500 mL· g^-1 urea, cationic surfaetant CTMAB and HA can increase adsorption of sulfa- monomethoxine in soil.
