Complexing sorbents POLYORGS —
series of selective polymeric sorbents with different complexing groups.
(Trade mark POLYORGS. Certificate
¹ 68715. 27.04.81 (RV).
These sorbents are designed for:
- sorptive preconcentration of noble, rare and
heavy metals from solutions for their consequent determination for analysis of
complex natural and industrial objects;
- recovery of noble and other metals from
technological and waste solutions.
POLYORGS sorbents are
characterized by
- high selective action, high sorptive capacity,
fast kinetic and chemical stability.
Those sorbents are used in form
of granules, powders, filters and fibrous materials.
POLYORGS sorbents provide
selectivity and high degree of metals extraction from solutions, simplicity and
quickness of samples preparation, decrease of limits of elements determination,
decision of problem of comparative sample's preparation.
For sorption extraction of
platinum metals are used
POLYORGS IV, V, VI, XI, XV,
XVII, XVIII, XXI, XXVI, XXVII.
For sorption preconcentration of
heavy metals are used
POLYORGS VII, IX, XII, XVI, XXII,
XXIV.
Sorbents POLYORGS IV, XI, XV, XVII,
XVIII, XXI, XXII, XXVI and XXVII may be
used in form of "filled" fibrous materials.
