Abstract
An integrated scheme for chemical analysis of soda-lime-silica glass and a few other silicate raw materials, having the following significant features, has been developed.
(a) Nickel and teflon wares have been introduced in the place of costly platinum articles; (b) interferences due to nickel as contaminant during fusion and silica from the matrix have been overcome by external addition of Al3+ as collector and O-phenanthroline as the masking agent; (c) use of toxic KCN which is invariably used in the common analytical processes has been done away with; and (d) the time and cost of an analysis have been drastically reduced.
Following the developed scheme, samples of soda-lime glasses, clays etc have been analysed. The results show a satisfactory conformity with those obtained by standard methods.
