Abstract
A method for determing calcium in sodium at 2 ppm or more is described. The matrix sodium was removed by vacuum distillation at 360 deg C and 5 x 10{sup -3} Pa. The calcium in the residue was determined by atomic absorption spectrophotometry. The recovery rate of this method was satisfied in experiments of adding 2{approx}500 ppm calcium to 1{approx}4 grams of high purity sodium. The relative standard deviation was at 5.3%{approx}7.2%. The possible loss of calcium and its compound resulting from distillation had been investigated. The interference and suppressing methods were also studied.
