A RAPID METHOD FOR DETERMINATION OF SILICON CONTENT IN BLACK LIQUOR BY UV SPECTROSCOPY

This paper describes the development of a simple UV spectroscopic method for determination of silicon content in black liquor. The method is based on the fact that Si (IV) can react with ammonium molybdate to form Si-Mo heterophony acid in an acidic condition (pH=4). The absorption peak of α-Si-Mo h...
