Iranian chemists from Tarbiat Moallem University of Azarbaijan succeeded in the precise measurement of salicylic acid drug in the solid phase extraction from biological media by using nickel-aluminum layered double hydroxide nanoparticles.
"In this research, solid phase extraction (SPE) method was used to extract salicylic acid drug from biological media with a complex matrix such as blood serum, plant tissue, medicine samples and so forth," Dr. Hossein Abdolmohammadzadeh, a member of the scientific board of Chemistry School of Tarbiat Moallem University of East Azarbaijan province, told INIC.
"SPE is the most appropriate method to remove the complex matrix, and it is very cost-effective and simple. Selecting the solid phase is the most important factor in solid phase extraction. Due to their high ratio of area to volume and their high chemical and thermal stability, nanoparticles improve the efficiency of solid phase extraction method significantly. In the present study, layered double hydroxide (LDH) nanoparticles were used as the solid phase in the SPE method," he added.
Elaborating on the procedure of the research, Dr. Abdolmohammadzadeh said, "In order to study the performance of the suggested method in the measurement of salicylic acid, we used this method to measure salicylic acid in biological samples, medicine compounds, and herbal samples."
"The results indicated the high performance of the suggested solid phase extraction method by using layered double hydroxide nanoadsorbents in the real sample analysis and its desirable accuracy."
Nanoadsorbents based on layered double hydroxides can be used in the purification of industrial and hospital wastewater due to their high adsorption capacity. Moreover, such compounds are biodegradable and they can be recycled very easily. Therefore, such adsorbents have a long life and they can be used in the removal of pollutants in several stages.
