Pesticides can be found at microgram levels in ground water or surface water. They usually come from intensive agricultural activities.
The most common pesticides found in water are Atrazine, DDT, lindane, Carbofuran, etc…
In natural waters, pesticides are present at ppb (microgram/L) level. Most of them are hydrophobic and easily removed by adsorption on ion selective synthetic adsorbent filters. Pesticides may appear as pollutants in water sources, having undesirable impacts to human health because of their toxicity, carcinogenicity, and mutagenicity or causing aesthetic problems such as taste and odours. These pesticides pollute the water stream and can be removed very effectively using low-cost adsorbents
LSF 904 is a synthetic adorbent. The process of adsorption arises due to presence of unbalanced or residual forces at the surface of liquid or solid phase. These unbalanced residual forces have tendency to attract and retain the molecular species with which it comes in contact with the surface. Adsorption is essentially a surface phenomenon. Adsorption is a term which is completely different from Absorption. While absorption means uniform distribution of the substance throughout the bulk, adsorption essentially happens at the surface of the substance. When both Adsorption and Absorption processes take place simultaneously, the process is called sorption.
Adsorption process involves two components Adsorbent and Adsorbate. Adsorbent is the substance on the surface of which adsorption takes place.Adsorbate is the substance which is being adsorbed on the surface of adsorbent. Adsorbate gets adsorbed.
Adsorbate + Adsorbent gives rise to Adsorption
Major types of adsorbents in use are: activated alumina, silica gel, activated carbon, molecular sieve carbon, molecular sieve zeolites and polymeric adsorbents. A broad range of synthetic, non-ionic polymers is available particularly for analytical chromatography applications .Resins such as phenol formaldehyde and highly sulphonated styrene/divinyl benzene macroporous ion exchange resins can be pyrolysed to produce carbonaceous adsorbents with surface area up to 1100 m2/g. These adsorbents tend to be more hydrophobic than GAC. Most adsorbents are manufactured (such as activated carbons), but a few, such as some zeolites, occur naturally. Each material has its own characteristics such as porosity, pore structure and nature of its adsorbing surfaces.
Pore sizes in adsorbents may be distributed throughout the solid. Pore sizes are classified generally into 3 ranges: macropores have “diameters” in excess of 50-nm, mesopores (also known as transitional pores) have “diameters” in the range 2 – 50-nm, and micropores have “diameters” which are smaller than 2-nm. Many adsorbent materials, such as carbons, silica gels and aluminas, are amorphous and contain complex networks of inter-connected micropores, mesopores and macropores. In contrast, pores in zeolitic adsorbents have precise dimensions.
LSF 904 Pesticide Residual Removing Resins can be regenerated . Regeneration of the resin is also a feature of ion exchange. The resin is flushed free of the newly-exchanged ions and contacted with a solution of the ions to replace them. Regeneration is initiated after most of the active sites have been used and the ion exchange is no longer effective. With regeneration, the same resin beads can be used over and over again, and the ions that we are looking to get out of the system can be concentrated in the backwash effluent, which is just a term for the spent fluid used to regenerate the ion exchanger.
Nowadays, the ion exchange substances are used almost exclusively under the name of resins. There are two categories of resins: the resins of the gel type and those of the macroporous or loosely cross-linked type. Their basic structure is identical: the macromolecular structure is obtained in both cases by co-polymerization. The difference between them lies in their porosity.
|Gel type resins have a natural porosity limited to intermolecular distances. It is a microporous type structure||Macroporous type resins have an additional artificial porosity which is obtained by adding a substance designed for this purpose.|
The exchanger is known as monofunctional if there is only one variety of radicals and it is called polyfunctional if the molecule contains various type of radicals.
About LSF 904 Pesticide Residual Removal Resins
SEPLITE® LSF 900 fruit/vegetable juice treatment resins are a series of styrene divinylbenzene copolymers of highly cross‐linked non‐functional adsorbent resins.
LSF 900 resins are specially designed for decolourisation, improvement of physical and chemical indexes including transmittance and turbidity, removal of harmful substances, such as patulin and pesticides, and increase the colour stability as well. Besides industrially applications in fruit juice, such as apple, orange , pear, pineapple, grape and pomegranate
juice treatment, LSF 900 series resins are also used for a wide range of recovery applications of high value materials and purification in other food processing applications.
LSF 904 is specially designed for remove harmful substances such as patulin and pesticide from fruit and vegetable juices. It can also be used for removing pesticides from potable water.
