Photocatalytic activity and statistical determination of ball-shaped zinc oxide NPs with methylene blue dye

ABSTRACT

Ball-shaped zinc oxide nanoparticles (ZnO-BNPs) were synthesized via a chemical solution process and the obtained BNPs used in a photocatalytic degradation process against methylene blue (MB) dye showed excellent photocatalytic properties (efficiency 72.37%). The analytical parameters, such as validity, reliability, accuracy, precision, linearity, range, limit of detection (LOD), limit of quantitation (LOQ), selectivity, specificity, and stability, were applied to confirm and fix the effective concentration of BNP suspension solution, affected by MB dye. The absorption spectra of ZnO-BNPs, MB dye, and ZnO-BNPs with MB dye were recorded at a maximum absorbance of λ_max 480, 650, and 690 nm, respectively.
