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。

关 键 词:无磷活性炭  土壤有效磷  吸附作用

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
