Optimizing the Sensitivity of Particulate Silica Quantification by Molybdenum Blue Absorbance Spectrometry
(2018-04)
The optimum initial pH (before addition of molybdate) for the dissolution of silica to form HPA is approx. pH 10. This may be due to the balance between enhanced silica solubility at high pH and the optimal (low) pH of the ...
