文摘
Evaluation of TXRF capabilities for AgNPs determination in soil adsorption studies LODs for Ag are about 40 μg·L− 1 for liquid samples and 1.7 mg·kg− 1 for solid samples. AgNPs are totally adsorbed in < 6 h being soil properties important. Results of AgNPs quantification by TXRF were comparable to ICP-OES. Direct analysis of soil is possible by the suspension of only 50 mg of sample.
