I am planning to determine the efficiency in the removal of chloride and sulfate ions by adsorption onto calcium peroxide. I would like to know at what wavelength should I be measuring the absorbance and is it possible?
I think a turbitity meter ( NTU ) will be more appropiate than UV-VIS spectrophotometer for Chloride and Sulphate pptions . This instrument is specific to measure to measure turbidity against a standard turbidity like colorimetry .
