In this study, the adsorption of amoxicillin onto activated carbon was investigated. The effect of particle size and the effluent flow rate was discussed as well as the kinetics and isotherm of adsorption equilibrium. The isotherm equilibrium studies showed that the Langmuir model was appropriate for describing the adsorption equilibrium of amoxicillin onto the activated carbon. Furthermore, th...

Rice husk ash (RHA), an agricultural waste, was used as biosorbent for the removal of Iron(II) and Manganese(II) ions from aqueous solutions. The structural and morphological characteristics of RHA and its elemental compositions before and after adsorption of Fe(II) and Mn(II) were determined by scanning electron microscopic (SEM) and X-ray fluorescence (XRF) analyses. Batch experiments were ca...

This study aims to investigate the application of two calix[4]arene derivatives named 5,11,17,23-tetra-(t-butyl)-25,26,27,28-tetrahydroxycalix[4]arene (TBCA) and 5,11,17,23-tetra-(t-butyl)-26,27,28-tribenzoyloxycalix[4]arene (TBMTCA) as adsorbents Pb(II) from aqueous solution in a batch system. Adsorption was carried out by varying pH solution, exposure time, concentration. The kinetics evaluat...

This study aims to comprehensively investigate the current advances in water treatment technologies for elimination of heavy metals using biomass-based adsorbents. The enhancement adsorption capacity biomass materials is achieved through surface modification, which increases their porosity and area. therefore focuses on impact different modification techniques capacity, as well evaluation adsor...

In the research work, adsorption equilibrium, kinetics, thermodynamics and dynamic separation of magnesium calcium ions from industrial wastewater by new strong acid cation resin SPVC (sulphonated polyvinylchloride) were investigated. The sorption capacity studied was 3.78 mmol/g 3.74 for ions, respectively, according to Langmuir isotherm. It found that pseudo−first−order model better fitted ki...

In this study, nano-TiO2 was employed for the adsorption of chloroform from aqueous solution in batch equilibrium experiments to investigate its adsorption properties. The effects of pH, initial chloroform concentration and nano-TiO2 dosage were also investigated. Optimal conditions for chloroform removal by nano-TiO2 have been then identified. Results of equilibrium experiments showed that the...

Background: Considering the severe health and environmental hazards caused by the entry of diazinon toxin into water resources, its removal is very important. Given the high costs of imported adsorbents, this research attempted to evaluate, for the first time, the efficiency of Iranian activated carbon in removing diazinon from aqueous solutions. Methods: In this batch experimental study, the ...

In this study, Ni NPs were produced by biosynthesis method with the help of phytoconstituents present in Sahadevi plant (Vernonia cinerea) ethanoic extract namely nickel nanoparticles (SNPs). SNPs characterized using XRD, FT-IR, HR-FESEM. XRD study shows crystalline nature SNPs. employed as bioadsorbent for elimination dyes like cationic (BG) and anionic (CR) from aqueous media. Adsorption capa...
