| 摘 要： | 复混肥中有效磷含量是复混肥单一养分的一项重要控制指标,它的快速、准确分析关系到工艺能否依据此来调整原料配比,生产出合格的复混肥产品。国标中采用的是磷钼酸喹啉重量法测定有效磷含量,该法准确度高,但操作步骤繁琐,耗时较长,约需3．0h。对于中控分析来说,这样报出的数据比较滞后,无法满足工艺需要。经过实验,选择用偏钒酸铵分光光度法测定有效磷含量。该法操作简便、快速,仅需30-50min即可完成测定,大大提高了工作效率,准确度较高,符合中控分析的要求。

| Abstract: | The content of effective phosphorus is an important index of mixes fertilizer Nutrient. How to fastly, accurately analyses it is related to raw material prompt and . qualified proportion producing. GB code has high accuracy, but its sequence of operation is troublesome and durational, unable to meet the process needs. Metavanadic acid ammonium spectrophotometric method makes the operation simple, fast, accurate and tallies the controls analysis request. |
