Abstract
The amount of chromium in feed was determined by FAAS.The interferences of coexistence elements were depressed with 5g/L of NH_4Cl.The method is rapid and simple.The detection limit is 6.26μg/L in the range of 92.8%—102.3% with relative standard deviation of less than 3%.
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.
