However, equilibrium sorption studies for temperature effect revealed that temperature elevation improves ion sorption for several studied sorption processes using chemically prepared ion exchangers
belong to a class of insoluble salts containing acids or bases.
The thermodynamic parameters entropy (S) enthalpy (H) and free energy (G) changes are computed which reveal that the chromium removal from tannery wastes by ion exchangers
is an endothermic physical sorption and entropically driven process.
2001), these elements are efficient ion exchangers
for the removal of heavy metals from aqueous solutions.
Recovering even small amounts of metal Traditionally, metal ions are removed from solutions with the help of chemical coagulants or ion exchangers
, which usually require adjustments to the solution's pH or significant extra energy in order to function efficiently.
are the older and somewhat less sophisticated technology.
The production of ultrapure water for the pharmaceutical or semiconductor industries requires high-quality ion exchangers
Such systems have been available for many years, but now, Mettler Toledo Intelligent Sensor Management (ISM) technology takes optimizing the use of ion exchangers
to a new level.
Union Showa also manufactures and develops various Ion Exchangers
at its Yokkaichi Plant, Mie Prefecture for nuclear waste remediation.
Validity and perspectives of a choice of furfural as a raw source for creation ion-exchange polymers is caused by presence in its structure of the heterocyclic groupings necessary for receiving ion exchangers
with the prescribed properties, namely, thermal and chemical stability, mechanical durability and radiation stability.
Phyllosilicates having a negative surface charge should be promising ion exchangers
for Hg(II) ions.
The target of this contract includes engineering, procurement, manufacturing, supply, site construction and erection and commissioning of variety of equipment like distillation columns (around 1 meter diameter x 52 meter height), tanks and vessels including large diameter dyke tanks, canned pumps, heat exchangers, ion exchangers
, de-contamination & laundry equipment, etc.
