Abstract
Spectrophotometry is a method of analysis that is based on the measurement of light absorption by a lane monochromatic colored solution at a specific wavelength using a prism or diffraction grating monochromator and detector vacuum phototube or photon vacuum tube. Measurements were made every 10 minutes. The observation showed a decrease in the levels of Mn in the minutes to 0; 10; 20; 30; 40; 50 respectively, are 0.714 ppm; 0.698 ppm; 0.493 ppm; 0.328 ppm; 0.109 ppm; 0,027 ppm. Keywords : Water Demineralization , Metal SO42- , Spectrophotometry
