According to Mehr news agency, citing Tehran University, Ariana Fatemi, a master’s stude in analytical chemistry, under the supervision of Hassan Sarshti, a faculty member of Tehran University, succeeded in syhesizing four new nanocomposite materials and investigating their effectiveness in removing pesticides as part of her research project in the laboratory of analytical chemistry.
In this research, the structure of nanocomposites was ideified and recorded using the techniques of electron microscopy, X-ray diffraction and infrared spectroscopy. These compounds are designed based on trimetallic double layer hydroxide including copper, nickel and lahanum and modified with compounds such as L-cysteine, EDTA and alginate biopolymer.
The results of the tests showed that these adsorbes have the ability to remove about 90% of pesticides from water and soil samples of paddy fields, and their reusability is maiained up to 10 times with an absorption capacity of 357 to 476 mg per gram of adsorbe.
The result of this scieific achieveme has been the publication of two articles in prestigious iernational journals such as Separation Science and Technology and Iernational Journal of Biological Macromolecules with high impact factors, which shows the importance and scieific quality of this research.
