summary
A TAPPI test method for identifying and estimating melamine resin in paper using ultraviolet spectrophotometry.
description
TAPPI T 493 cm-10 provides procedures for the qualitative identification and semi-quantitative determination of melamine resin in paper. The method includes micro and macro procedures for extracting and hydrolyzing resin with hydrochloric acid, measuring absorbance at specified ultraviolet wavelengths, evaluating potential interferences, calculating resin content, and reporting results based on moisture-free paper weight. It also covers required apparatus, reagents, specimen preparation, calculation factors, precision, safety considerations, and supporting technical information.
Application Scope: Intended for laboratories, paper manufacturers, quality control teams, and researchers analyzing melamine resin in paper and related paper products.
