摘要:以微囊藻为吸附载体、卡波树脂为包衣剂制备戊唑醇农药缓释剂,对微囊藻和缓释剂进行了表征,研究了微囊藻的吸附和释放行为.结果表明,30℃下戊唑醇在乙醇和异丙醇中的饱和吸附量分别为18.68和20.1mg/g,平均每个微囊藻吸附1.04×109个戊唑醇分子.包裹10%卡波树脂的缓释剂具有很好的缓释功能,在乙醇/水(1:1,φ)介质中累计释放时间长达204h,累积释放率为74.5%.
The controlled release formulation of tebuconazole (Teb) was prepared using microcystis (MC) as carrier and carbopol resin as matrix. The MC powder and release formulation were characterized by XPS, FT-IR, SEM, etc. Its adsorption and release behavior are measured by ultraviolet visible spectrophotometer. At 30 ℃, the adsorptive capacity of Teb is 18.68 mg/g in ethnol and 20.1 mg/g in isopropanol, respectively. The adsorption density is 1.04×10^9 Teb molecules per MC. The controlled release formulation of 10% carbopol release rate is 74.5% for 204 h in ethanol-water solution (1:1, φ).
