After leaving the dialyzer, dialysate flows through a series of three
sorbent cartridges that adsorb ammonium, small and medium-size solutes, and organic compounds.
05 g mL-1
sorbent at pH 2 at 200 rpm for 2 hr shaking time.
The use of natural organic
sorbents to clean-up oil spills presents many advantages due to simplicity of approach and the inexpensive nature of these materials.
The sorption assays were performed for the unclassified
sorbents, that is, without granulometric classification, and for the [less than or equal to] 180; 180-425; 425-850 and 850-3350 [micro]m granulometries, using the method described by Lee, Han, and Rowell (1999), where 0.
The
sorbents based on xerogels of zirconium (ZOH), aluminum (AOH) and manganese (MOH) oxyhydroxides were prepared by sol-gel method during the hydrolysis of metal chlorides (zirconium oxychloride ZrO[Cl.
2009) and then the dithiooxamide functionalised MWCNT was used as a
sorbent to remove the toxic Hg(II) ions in different aqueous solutions.
Results showed that the synthesized composite can be used as an effective
sorbent to purify water contaminated by fluoride due to its simple and quick separation, high efficiency and the lack of the creation of secondary pollution in the solution.
The synthetic material alleviates the challenges associated with natural resources such as availability and consistency because the
sorbent is lab-manufactured and undergoes strict QC guidelines.
In recent years several works have been conducted to use natural biodegradable
sorbents in the removal of oil spills e.
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].
An improved sorption efficiency of the coal
sorbents at neutral pH was obtained in mixture with chitosan, namely for oxihumolite at sorption of Eu(II) and Co(II).
Koros, Qiu, and Zhang have developed functionalized polymeric
sorbents to remove low-level contaminants from fluid streams.
