| Abstract: | Available molybdenum in soil was determined by graphite furnace atomic absorption after supersonic dissolving and APDC-MIBK extraction.Ascorbic acid was used as matrix modifier.The recovery of detected elements from soil varied from 95% to 105% and RSD was 1.35% for the soil samples.The method was rapid, accurate,sensitive and simple.The obtained results agreed well. |
