Abstract: Sulfamonomethoxine is a veterinary antibiotic drug, which can be absorbed by soil. The adsorption behavior of sulfamonomethoxine in soil and influence of nitrate, urea, anionic surfactant dodecylbenzene sulfonate (SDBS), cationic surfactant hexadecyltrimethyl\|ammonium bromide (CTMAB) and humic acid (HA) on it were studied. The results showed that: the distribution coefficient Kd of sulfamonomethoxine in the soil was 18.9 mL·g-1, organic 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, increasing its mobility in soil. 500 mL·g-1 urea, cationic surfactant CTMAB and HA can increase adsorption of sulfamonomethoxine in soil.

Key words: sulfamonomethoxine, soil, adsorption, environmental substances, distribution coefficient Kd, organic carbon distribution constant KOC
