摘要
以无水乙醇作溶剂,利用超声波提取复混肥料中的缩二脲,用分光光度法测定复混肥料中缩二脲含量。结果表明:该方法回收率为96.3%～103.60%,标准偏差为0.011%～0.052%,且所用仪器简单、容易操作、测定速度快。
A method was developed for biuret content in compound fertilizer by spectrophotometry. Using ethanol as a solvent to extract biuret by ultrasound. The results showed that the recovery was 96.3% - 103.60%, the standard deviation was 0.011% - 0.052%, and the equipments used in this experiment were simple, easier - to - use, and faster.
