PENENTUAN TIMBAL SECARA SPEKTROFOTOMETRI UV-VIS DENGAN PENGOMPLEKS ALIZARIN RED S

LEAD DETERMINATION BY UV-VIS SPECTROPHOTOMETRIC USING ALIZARIN RED S AS COMPLEX AGENT

Author :
Wulansari, Alita Tri 




ABSTRAK

Telah dipelajari penggunaan Alizarin Red S dalam penentuan timbal II secara spektrofotometri. Alizarin Red S bereaksi dengan timbal membentuk kompleks berwarna kuning yang mempunyai serapan maksimum 0329 pada panjang gelombang 422 nm. Kurva kalibrasi linier pada konsentrasi 0-32 ppm dengan koefisien korelasi R sebesar 09975. Kompleks stabil dalam suasana asam pH 3 selama 20 menit.


ABSTRACT

The use Alizarin Red S on lead II determination with spectrophotometric method has been studied. This method is simple for determination lead. Alizarin Red S reacts with lead to form yellow complex that has maximum absorption at 0329 with wavelength 422 nm. Calibration curve is linear at 0-32 ppm with coefficient of correlation R 09975. Complex is stable in pH 3 acid condition for 20 minutes.
