Abstract :A method for preconcentration of Alinsert ignore into journalissuearticles values(III); prior to its determination by inductively coupled plasma-optical emission spectrometry insert ignore into journalissuearticles values(ICP-OES); was developed because the sensitivity of ICP-OES is insufficient for trace-level measurement of Alinsert ignore into journalissuearticles values(III);. The method is based on the use of Coriolus versicolor}-immobilized $\gamma $-Fe$_{2}$O$_{3}$ magnetic nanoparticles as a solid phase sorbent. The best experimental conditions were found as pH 6.0, 2.0 mL/min flow rate, 100 mg amount of C. versicoloron 150 mg of $\gamma $-Fe$_{2}$O$_{3}$ nanoparticles, and 500 mL of sample volume. The Alinsert ignore into journalissuearticles values(III); absorbed on biosorbent was eluted with 5.0 mL of 1.0 mol/L HCl. Limit of detection, limit of quantitation, linear range, correlation coefficient, relative standard deviation, and preconcentration factor were achieved as 0.03 ng/mL, 0.11 ng/mL, 0.2 to 20 ng/mL, 0.9994, 3%, and 100, respectively. Alinsert ignore into journalissuearticles values(III); was preconcentrated in different water and food samples after successful results were achieved in the case of certified reference samples.
