Abstract :In this study, anthocyanin-rich fermented black carrot juice insert ignore into journalissuearticles values(şalgam/shalgam); was used as a chromogenic agent in order to develop eco-friendly, low-cost, simple, fast, and practical both visible spectrophotometric and smartphone-based methods for the determination of Alinsert ignore into journalissuearticles values(III); ions in water samples. Formation of Alinsert ignore into journalissuearticles values(III);-anthocyanin complex results in a color change from red to purple in direct proportion to the increasing Alinsert ignore into journalissuearticles values(III); concentration. For the spectrophotometric analysis, the analytical response of the developed method between absorbance and logarithm of Alinsert ignore into journalissuearticles values(III); concentration exhibits a satisfying wide linear concentration range from 37.0 to 1850.0 µM. The LOD and LOQ values are 6.67 µM and 22.0 µM, respectively. For smartphone-based analysis, the analytical response of the developed method between B values and Alinsert ignore into journalissuearticles values(III); concentration obtained a linear concentration range from 18.5 to 111.0 µM. The LOD and LOQ values are 4.40 µM and 14.5 µM, respectively. LOD values are below the acceptable limit of Alinsert ignore into journalissuearticles values(III); in water according to WHO insert ignore into journalissuearticles values(7.41 µM); for both methods. The interfering effect of common water ions was investigated, and the observed interferences from Sn2+, Fe2+, and Fe3+ were easily eliminated using enough concentration of Na2EDTA without affecting the blank absorbance/B value of the Alinsert ignore into journalissuearticles values(III);−anthocyanin complex for two monitoring methods. The selectivity of the developed method was investigated in the presence of possible species such as benzoic acid, lactic acid, amino acids, and salt. Developed spectrophotometric and smartphone-based methods applied to real water samples and validated against the reference ICP-OES method at 95% confidence level using Student’s t- and F-tests.
