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20.1 mg/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, j)介质中累计释放时间长达204 h，累积释放率为74.5%.

Abstract: 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 1.04×109 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, j).

Key words: microcystis, tebuconazole, controlled release formulation, adsorption
