The study was carried to evaluate the ability of defatted seed Adansonia digitata (DFSE) remove methylene blue dye from contaminated water. optimum parameters such as contact time, particle size, absorbent dose, initial concentration, and pH were investigated by performing batch experiments models. kinetics isotherms adsorption evaluated varying concentration using parameters. time is 90 min re...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...

In this paper some kinds of interactions and communications in IEC 61499-based systems and the ways of their implementation on the basis of function blocks are presented. Examples of binary semaphores, " producer-consumer " problem and distributed data management system implementations are considered. Besides, the function block-based implementation of interpreted Petri nets, on the basis of wh...

Feather mites (Astigmata: Analgoidea and Pterolichoidea) are commensal ectosymbionts permanently living on avian hosts. The study was based parasitological examination of 59 bird specimens representing 28 species from the orders Accipitriformes, Apodiformes, Columbiformes, Passeriformes, Pelecaniformes, Strigiformes collected in Artvin, Samsun, Sakarya, Türkiye. We recovered 18 feather mite fam...

Acid and thermal treated sepiolite was organophilized by cationic exchange with several alkylammonium cations (octylammonium, hexadecylammonium, tetradecyltrimethylammonium, hexadecyltrimethylammonium). The adsorption capacity of BTEX from aqueous solutions evaluated through the isotherms performed in batch. results were analysed using three isotherm models: Freundlich, Langmuir Dubinin-Radushk...

The paper investigates the physicochemical regularities (kinetics and isotherm) of phosphorus beryllium recovery by sorbents based on polyacrylonitrile (PAN) fiber Fe(OH)3 obtained various methods: PAN or pre-hydrolyzed with precipitation FeCl3 ammonia, using ready-made electrochemically generated Na2FeO4, treated an alkaline solution as well their comparison granular aluminum oxide. Langmuir, ...

Abstract Adsorbed methane significantly affects shale gas reservoir estimates and transport in formations. Hence, a practical model for accurately representing adsorption behavior at high-pressure high-temperature is imperative. In this study, reliable mathematical framework that the absolute directly from low-pressure excess data applied to describe literature. This method provides detailed in...
