The method is based on the use of Coriolus versicolor-immobilized γ -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. versicolor on 150 mg of γ -Fe 2 O 3 nanoparticles, and 500 mL of sample volume. The Al(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. Al(III) was preconcentrated in different water and food samples after successful results were achieved in the case of certified reference samples.eninfo:eu-repo/semantics/openAccessAluminumBiosorbentFoodICP-OESMagnetic solid phase extractionPreconcentrationArticle43512171228WOS:0004891115000012-s2.0-8507380953710.3906/kim-1904-18Q3Q4
