EVALUATION OF THE POTENTIAL OF AGRICULTURAL WASTE PRODUCTS FOR THE TREATMENT OF TEXTILE DYE CONTAMINATED WATER

-- In this study, the peels of waste agricultural products (banana, orange, potato) used as biosorbent in order to remove textile dyes from aquatic solutions. Biosorption of the commonly used textile dye such as Acid Red P-2BX (AR) was investigated by the peels of different agricultural products. The waste peels of banana, orange and potato were prepared as dried and ash biosorbent. The effects of pH, biosorbent type, dye concentration, biosorbent dosage and temperature on dye biosorption were tested at batch scale level. The best removal of dye was performed by the banana peel. Biosorption by dried banana peel for AR dye was found to be 73.58% at optimum conditions. It was concluded that dried banana peels were effectively used in the treatment of textile dye- contaminated water.

Applications of Activated Carbon Sorbents Based on Greek Walnut

This article presents the results of the synthesis of carbon nanomaterials: Nanoscale materials obtained by carbonization of waste agricultural products (apricot kernel, Greek walnut (GW), rice husk). The results of physico-chemical characteristics of the obtained nanomaterials. Physico-chemical parameters of the synthesis of carbonized sorbents based on plant raw material are investigated along with the properties of these sorbents. The data of FTIR, ESR spectroscopy & BET-method, as well as electron microscopy are reported. It is stated that carbonized sorbents possess high specific surface area and porosity. Carboxylic, carbonyl, hydroxyl groups are detected on the surface of the synthesized sorbents. Separate fusicoccine and similar biostimulators effectively; remove LPS-endotoxines from blood plasma selectively. They may be used as carriers to introduce probiotics into intestine thanks to formation of stable colonies on their developed surface. A method of preparation of honeycomb monoliths from carbonized rice husk with developed mesoporous structure via modification of the porous structure by silica leaching has been developed.

Agricultural Residues from Pyrolysis and their application in Flotation / Zemědělské Odpady Po Pyrolýze A Jejich Aplikace Ve Flotaci

Abstrakt The paper deals with verification of floatability of a classical collector Montanol 551 and pyrolysis oils that were formed through pyrolysis of agricultural residues from basic industry and used in the flotation of black coal. The results imply that it is possible to produce collectors also from waste agricultural products, which may be applicable in the flotation of black coal.
