Principle: oxydation of a test portion in a Parr bomb under alkaline conditions to destroy organic matter and to solubilize the mineral matter. Formation of molybdosilicate complex and spectrometric measurement at a wavelength of 630 nm.
Abstract
Overview
ISO 5400:1984 defines a for the determination of total silicon in leather, expressed as SiO2. The method is designed to destroy organic matter, solubilize mineral content and develop a molybdosilicate complex whose blue coloration is measured spectrometrically at . The procedure is intended for routine laboratory use in tanning, quality control and material analysis.
