| 摘 要： | 用碳酸氢钠溶液浸提石灰性土壤测定有效磷含量时，起脱色作用的无磷活性炭对PO4^3-离子有明显的吸附作用，使测定结果偏低，文章通过实验证明了活性炭对PO4^3-离子的吸附作用，并提出了相应的解决方法。

| Abstract: | When determination the usable phosphorus in lime like soil , apparent absorption of non-phosphorus active carbon which decolorized things was observed for PO3-4 ions. This report experimentally proved that active did absorb PO3-4 and methods to solve the ＂absorption＂ trouble were correspondingly proposed of usable phosphorus in soil. |

| Keywords: | non-phosphorus active carbon usable phosphorus in soil absorption |
