| 摘 要： | 参照尿素中缩二脲的测定方法，通过条件试验，利用加入适量的碳酸钠和氢氧化钠，消除了测定复混肥中缩二脲过程中金属杂质的干扰，建立了复混肥中缩二脲的测定方法。通过制作工作曲线试验、精密度试验和回收率试验，验证了该测定方法准确可靠。该法的相对偏差为1．60％，加标回收率为98％-102％。

| Abstract: | By consuhing the method for the determination of biuret in urea, a method for the determination of biuret in compound fertilizers is established through experiments on conditions and the addition of appropriate quantities of sodium carbonate and sodium hydroxide to eliminate the interference from metal impurities in the process of determination. The accuracy and reliability of the method are verified by conducting experiments for the preparation of the working curve, precision and recovery. The relative deviation of the method is 1.60% and the marked recovery 98% - 102%. |
