摘要:
Filter-papers impregnated with iron oxides (''iron-strips'') are increasingly being used to estimate ''bioavailable'' phosphorus. This study shows that these strips, in addition to being able to adsorb phosphate ions, can also mediate the hydrolysis of a model organic phosphorus compound. It is proposed that the high correlation between bioavailable phosphorus and iron-strip available phosphorus is due in part to the strips' hydrolytic capability.
