摘　　要：研究了用火焰原子吸收光谱法测钙时PO_4^(3-)对钙的测定的干扰情况以及用有关方法消除PO_4^(3-)对钙干扰的效果。用La(NO_3)_3和EDTA单独消除PO_4^(3-)的干扰进行了实验研究,同时对有关问题作了讨论。对测定各种样品中的钙时消除PO_4^(3-)的干扰有一定的指导意义。We researched the PO4^3- interference and the elimination of the PO4^3- interference during determining calcium by FAAS. The elimination of the PO4^3- interference with La（NOs）s and EDTA was studied separately, meanwhile certain some questions were discussed. This paper has certain guidance in elimination the PO4^3- interference during determining calcium.
