چکیده
A method for methanol detection by an inexpensive device using a nanomaterial modified N-methylpolypyrrole (NMPPY) has been developed. Manganese-doped zinc sulfide quantum dots (Mn/ZnS-QDs) were synthesized and then characterized fluorescence spectrophotometer to study their spectroscopic properties. Mn/ZnS-QDs with NMPPy studied digital-image colorimetry optimize conditions detection. 2 mL of 3000 mg∙L–1 300 μL 1000 mg∙L-1 was chosen be detecting reagent determination. Under the optimum conditions, linear range found 2%v/v 50%v/v R-square 0.9434 sensitivity 3.569 ´ 10–3 (%v/v)-1, whilst limit (LOD) 19.5%v/v. The selectivity this also several solvents; it proven selective methanol. Furthermore, prototype simple created. analytical performances studied; linearity in 20%v/v 80%v/v 0.9918 3.38 10-3 (%v/v)-1. Finally, newly developed applied analyze samples hand sanitizer gel acceptable results.
