摘要
用甲醇作溶剂，在室温下对试样进行提取，在盐酸溶液─—氯仿中净化，用０．３ｍｏｌ／ＬＨＣｌ作参比和吸光度差值法建立了桑叶中多菌灵的紫外光谱测定方法，方法回收率在９０％～９６％之间，浓度在０～２０ｍｇ／Ｌ范围内呈线性关系。
With methanol as solvent , the salnples were soaked,stirred and extracted atroom temperature,and then purified by liquid─liquid distribution of aqueous HClsolution-CHCl_3.The contents of carbendazim in mulberry Leaves were determined byUV differential absorbance method using aqueous HCl(0. 3 mol/L)as reference. Therecovery was 90%～96%,and the linear range is 0～20 mg/L.
