Journal of the Society of Dyers and Colourists
The salt is best purified by recrystallisation, by treating it with hot water, filtering
as rapidly as possible, and rapid cooling, when the potassium persulphate is
separated in small prisms. On these Deing heated to redness, there remains ...

The North American Medical and Surgical Journal ...
This method consists in precipitating a meconate of lead by acetate of lead,
liberating the meconic acid by sulphuric acid, and then adding a solution of
persulphate of iron, which will produce a characteristic red colour. The Parisian
professor ...

The British Journal of Photography
On passing a current from a batteryof two accumulators through the solution for
some time, a considerable quantity of per-sulphuric acid is produced, and in
about a qu 1rter or half an hour potassium persulphate begins to crystal]ise out
and ...

Chemical Bioavailability in Terrestrial Environments
that remain in the soil after persulphate oxidation may be a measure of the
nonbioavailable or non-biodegradable fraction (Cuypers et al., 2000). In this
method, contaminated soil (5g) is mixed with potassium persulphate and
deionised water ...

Specialty Polymers: Materials and Applications
We have employed [25-27] five oxidants, namely: ammonium persulphate,
cerium(IV) sulphate, potassium dichromate, sodium vanadate and potassium
ferricyanide. The SRP of these oxidants ranges from 2.01 to 0.36 V vs. NHE. Pron

Printed Circuit Boards: Design, Fabrication, Assembly and ...
The formulations of ammonium persulphate containing sulphuric acid and
catalysed with mercuric chloride give a good etch factor and easy regeneration in
the closed loop system. But this system is costly as compared to other etchants
and its ...
