According to Mehr news agency, citing Tehran University, Ariana Fatemi, a master’s student in analytical chemistry, under the supervision of Hassan Sarshti, a faculty member of Tehran University, succeeded in synthesizing 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 identified 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 lanthanum and modified with compounds such as L-cysteine, EDTA and alginate biopolymer.
The results of the tests showed that these adsorbents have the ability to remove about 90% of pesticides from water and soil samples of paddy fields, and their reusability is maintained up to 10 times with an absorption capacity of 357 to 476 mg per gram of adsorbent.
The result of this scientific achievement has been the publication of two articles in prestigious international journals such as Separation Science and Technology and International Journal of Biological Macromolecules with high impact factors, which shows the importance and scientific quality of this research.
