| 摘 要： | Some soft and mud samples have been determined for eadmiun, lead, copper,nickel and cobalt by atomic absorption speetrophotometry with a high-temperature graphite tube, after their extraction with sodium diethylthiocarbonate into methy lisolutyl ketone. The tests of the effects of acidity on extraction and interference have been also carried out and the optimum conditions have been obtained. In addition, experiments on recoveries by this procedure have been performed for the elements in ppb amount. The recovery of the metals added to soil samples is made in the same manner and the precision values are given in this paper. This method is considered as to be applicable to the determination of soil and mud samples for the above-mentioned elements, of which the concentration is higher than 1 ppb.
