Chemistry, Physics and Technology of Surface| Zusammenfassung: | The process of obtaining of new biosorbents from apricot seed shells by oxidative-organosolvent processing in "acetic acid - hydrogen peroxide" medium has been studied. The structural and sorption properties of the materials obtained using physical and chemical methods were investigated. The effect of the reactants ratio in solution, as well as the duration of the modification process on the yield, content of cellulose, lignin, mineral components and on sorption properties of the products was studied. The dependence between the mineral content and the adsorption pore volume was shown. The positive effect of hydrogen peroxide application in the process of modifying of plant waste on cellulose content was estimated. Increasing the duration of modification increases the contribution of oxidative transformation of lignin into soluble products and decreases the yield of the lignocellulosic materials. The regularities of sorption of marker of low molecular weight toxins and non-steroidal anti-inflammatory drugs on obtained products were investigated. It has been found that the highest sorption capacity of obtained lignocellulosic sorbents towards methylene blue and Sodium Diclofenac corresponds to the samples with polysaccharide content 60 %. It has been also found that the sorption equilibrium occurs within 120 minutes of contact. The obtained results demonstrate the feasibility of application of such lignocellulosic carriers in the production of prolonged action drugs. |
