초록
This experiment was attempted to establish the optimal condition, e.g., the effects of pH, interferences of other elements, for the determination of the inorganic elements in the paddy soils by atomic absorption spectrophotometry. Inorganic elements of 100 paddy soils which were sampled in Jeon bug provincial farm land were determined by atomic absorption spectrophotometer in that condition. The results obtained in this experiment are summarized as follows: 1) The optimal pH for determination of inorganic elements in paddy soils is about 7.0. 2) It was investigated that the absorbance of potassium was increased, and that of calcium, magnesium and zinc was decreased by adding of
