Determination of calcium and magnesium of laver by xylenol orange isosbestic point spectrophotometry

CHEN Xiao-hong;DA Gu-la;XU Ling;College of Chemical Technology, Inner Mongolia University for Nationalities;  
In pH=10.5 NH3-NH4 Cl buffer solution, calcium, magnesium and xylenol orange formation coloured coordination complex. The article has researched determination of calcium, magnesium by xylenol orange isosbestic point spectrophotometry. The results showed that absorption wavelength λ=584 nm. It has been found that Ca2+, Mg2+ content according with Lambert-Bill laws from 0~6.0×10-5 mol/L.The minimum concentration detected is 7.2×10-6 mol/L. The method is applied determination of laver, the relative standard deviation was 3.6%, recovery is 96.0%.
