Abstract
Graphite furnace atomic absorption spectrometry is used to detect molybdenum in water samples with hot coating graphite tube which is no platform when ashing temperature is 1850 degree,and atomic temperature is 2380 degree.Six samples are detected with excellent accuracy and precision,among which relative standard deviation is less than 10%,and fraction product recovery is between 96.6 to 101 percent.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
