摘要:We proposed a new technique for the disposal of solid plant waste in the food industry, specifically solid shell of Prunus armeniaca seeds, by oxidative treatment with a hydrogen peroxide solution in an acetic acid medium, which makes it possible to obtain effective sorbent materials. We investigated the effect of oxidant concentration and time of the process on structural and sorption properties of plant sorbents. The experimental-statistical models of the process were obtained by employing a method of mathematical planning based on the mathematical processing of acquired experimental data. The optimal conditions for conducting the process using the generalized Harrington desirability function were determined. It was established that the optimal parameters that make it possible to obtain effective sorbents with the yield, the content of cellulose, lignin, and the efficiency of extracting methylene-blue from an aqueous solution of 50.3 %, 58.2 %, 12.7 % and 91.4 %, respectively, are the concentration of peroxide hydrogen of 9 % and a process time of 120 min. The application of the proposed technology enables efficient disposal of solid plant wastes, and obtaining the sorbents with high sorption characteristics. Such materials could be used in environmental science to solve the problems related to the contamination of water bodies by organic compounds, as well as enterosorbents in medicine and veterinary medicine.
