【摘要】 采用十二烷基硫酸钠(SDS)对阿维菌素-类水滑石(AVM-LDHs)杂化物疏水表面进行修饰,成功地将固体表面的单吸附层转变为亲水的表面活性剂双层,制备了水分散型纳米复合物。调节处理温度、时间、SDS和无机盐用量等条件,水分散纳米复合物悬浮率可达到90%以上。实验结果表明,该复合物对AVM具有较好的控释性能,并且提高了农药的紫外光稳定性。更多还原

【Abstract】 Water dispersible avermectin-layered double hydroxide nanocomposites were successfully prepared using sodium dodecyl sulfate as surface modifier.Concentrations of sodium dodecyl sulfate and NaCl had important effects on the product suspensibility,the obtained value of which was higher than 90%. Experimental results showed that the prepared nanocomposites could well control the release of avermectin,and protect effectively the pesticide against UV light decomposition.更多还原
