| 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 tefton 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 AI"+ as collector and 0-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 |
