Chitosan has been used as a sorbent
in this research to eliminate fluoride from aqueous environments.
Because the compounds were both neutral and basic in nature, an SPE sorbent
that has hydrophobic and strong cation-exchange properties was chosen (Figure 2).
For more than 10 years the research team of general chemistry subdepartment of Belgorod State National Research University (NRU "BelSU") has been developing effective sorbents
for purification of waste, industrial, natural and drink water from above mentioned pollutants, using for this purpose both mineral sorbents
based on natural and modified aluminosilicates and based on products of pyrolysis and hydrothermal activation of waste of plant products and woodworking enterprises [9, 10].
Koros, Qiu, and Zhang have developed functionalized polymeric sorbents
to remove low-level contaminants from fluid streams.
Adrian, A review of potentially lowcost sorbents
for heavy metals.
This step was essential to minimize the possibility of base-catalyzed auto-oxidation of carbonaceous sorbents
in the presence of oxygen .
Tests of sorbent
injection systems, the most mature mercury control technology, were conducted on a variety of coal types and boiler configurations--that is, on boilers using different air pollution control devices.
Available as pads, rolls and split rolls, the EverSoak Oil Only products with patent-pending Q-CEL technology are high-performance sorbents
for oil-based spills large and small.
Technologies Corporation, which provides proprietary mercury reduction sorbents
, systems and services for coal-fired power plants, has been named a finalist in the Platts Global Energy Awards competition for the Commercial Technology of the Year.
The effectiveness of the air cleaners depends on the properties and amount of sorbents
, the packing (or coating) density of the sorbent
layer, the velocity and flow rate of air passing through the sorbent
media, the properties of the volatile organic compounds (VOCs), and environmental conditions such as relative humidity and temperature.
and formats have expanded SPE's applications as well its ease of use and flexibility.
To overcome the pH limits for silicagel sorbents
a wide range of polymer sorbents
are used [7, 8].
