水稻土分布于全球,并长期处于水饱和状态,这与大多数陆地生态系统不同。为了更好地了解抗生素在稻田土壤中的环境风险,本研究选择磺胺嘧啶(SDZ)作为典型抗生素。我们研究了其吸附行为以及土壤溶液性质的影响,例如 pH 条件、溶解有机碳 (DOC)、离子浓度 (IC) 和 Cu2+ 的共存。结果表明:(1)土壤溶液pH和IC的变化降低了水稻土对SDZ的吸附。 (2)DOC的增加有利于SDZ在水稻土中的吸附。 (3)Cu2+共存增强了SDZ对有机成分的吸附,但降低了粘性土对SDZ的吸附能力。 (4)进一步的FTIR和SEM分析表明,络合可能不是稻田土壤中Cu2+和SDZ共吸附的唯一形式。基于以上结果,可以得出结论,土壤溶液性质和共存阳离子决定了SDZ在水稻土中的吸附行为。
Paddy soils are globally distributed and saturated with water long term, which is different from most terrestrial ecosystems. To better understand the environmental risks of antibiotics in paddy soils, this study chose sulfadiazine (SDZ) as a typical antibiotic. We investigated its adsorption behavior and the influence of soil solution properties, such as pH conditions, dissolved organic carbon (DOC), ionic concentrations (IC), and the co-existence of Cu2+. The results indicated that (1) changes in soil solution pH and IC lower the adsorption of SDZ in paddy soils. (2) Increase of DOC facilitated the adsorption of SDZ in paddy soils. (3) Cu2+ co-existence increased the adsorption of SDZ on organic components, but decreased the adsorption capacity of clay soil for SDZ. (4) Further FTIR and SEM analyses indicated that complexation may not be the only form of Cu2+ and SDZ co-adsorption in paddy soils. Based on the above results, it can be concluded that soil solution properties and co-existent cations determine the sorption behavior of SDZ in paddy soils.
