| 摘 要： | 在GB18877 2002《有机-无机复混肥料》的基础上,规定称样量范围,改变氧化剂溶液的配制方式,用改进的重铬酸钾容量法测定有机-无机复混肥料的有机质含量,回收率达99.76%,相对标准偏差0.25～0.43%,准确度及重现性均优于标准方法。

| Abstract: | On the basis of the GB18877-2002 standard for organic-inorganic compound fertilizers, An improved protocol on the sample weight range and the oxidant-solution preparation were proposed for determination of the organic matter in twelve organic-inorganic compound fertilizers by potassium dichromate volumetry, giving a mean recovery of 99.76% and RSD values from 0.25% to 0.43%. The accuracy and reproducibility of the improved method are better than that of the standard method. |
