Preparation and performance of acetaniprid-lignin quaternary ammonium salt-bentonite slow release formulation.

  • 摘要: 为了提高木质素产品的附加值,以木质素季铵盐为改性剂、钠基膨润土为原料,制备了不同季铵盐载量的膨润土。通过FTIR表征改性膨润土结构,并采用XRD分析其底面间距。以啶虫脒为药物释放的对象、改性膨润土作为释放的主要载体,利用浸渍吸附的方法制备出了啶虫脒缓释剂,并研究其缓释性能。结果表明:啶虫脒在改性膨润土上的吸附量随着木质素季铵盐载量的增加而先增大后减少。当木质素季铵盐载量相当于膨润土阳离子交换容量(CEC)的0.8倍时制备的改性膨润土(L-0.8Bt)对啶虫脒的吸附效果最佳,最大吸附量为315 mg/g。制备啶虫脒缓释剂的最佳工艺条件为L-0.8Bt用量0.02 g、吸附时间4 h、啶虫脒质量浓度500 mg/L、pH值6。药水比例和温度对载药L-0.8Bt的缓释快慢有一定影响。
