Determination of Available Molybdenum in Soil by Tamm Solution Extraction and Graphite Furnace Atomic Absorption Spectrometry
A method for the determination of available molybdenum in soil samples by Tamm solution ex-traction and graphite furnace atomic absorption spectrometry has been presented.The correlation coeffi-cient of available molybdenum standard curve is 0.9995,the detection limit is 0.005mg/kg,and the quanti-tation limit is 0.018mg/kg.The applicability of the method has been investigated by using certified refer-ence materials.The measured value of the method is basically consistent with the certified value,the rela-tive error(RE)is less than 4.17％,and the relative standard deviation(RSD)is less than 7.87％.The de-tection limit of the method is low,the precision and accuracy are good,which will meet the requirements of soil sample testing and simplified the work flow.The work efficiency has been improved.It is suitable for the determination of available molybdenum in batch soil samples.
