The study's objective is to produce Nano Graphene Oxide (GO) before using it for batch adsorption remove heavy metals (Cadmium Cd+2, Nickel Ni+2, and Vanadium V+5) ions from industrial wastewater. temperature effect (20-50) °C initial concentration (100-800) mg L-1 on the process were studied. A simulation aqueous solution of was used identify isotherms, after experimental data collected, sorpt...

zinc (zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. contradicting evidence has been reported for factors influencing zn behavior in soils. the aim of this study was to investigate the zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (na+, k+ and h2po4, no3 and cl backgrounds). iso...

In this study, a new cationic P(AAm-AETAC) hydrogels were prepared by radical addition reaction in aqueous solution with acrylamide and [2-(acryloyloxy)ethyl] trimethylammonium chloride) comonomers the presence of ethylene glycolmethacrylate. Hydrogels characterized spectroscopic, surface, thermal analysis. The hydrogel does not undergo any structural degradation effect heat up to 250 oC.The ad...

This study presents Pb(II) recovery/removal from water solutions using two different commercial ion-exchange resins, i.e., Dowex G-26 with sulfonic functional group and Puromet™ MTS9570 phosphonic groups. Overall, 100% by both resins was obtained at solution pH 3.5, resin dosage 25 g/L, adsorption time 30 min, room temperature, initial concentration 1000 mg/L. Langmuir, Freundlich, Temkin isoth...

an ion imprinted polymer (iip) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of sr (ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde) (nipaf). the sorbent was characterized by fourier transform infrared spectroscopy and was used for solid ph...

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...

In recent years, great focused has been placed on the development of low-cost adsorbents to be used for applications regarding treatment wastewater. this study, Leucaena leucocephala peel (LLP) was adsorption methylene blue from aqueous solutions. The experiments were conducted at seven concentrations (15, 30, 45, 60, 75, 90, 105 mg L-1) and three temperatures (298, 308, 318 K). obtained data a...

Rice fields of Meghalaya especially in the coal mining belt receive water contaminated by effluents from mines that are known to carry harmful heavy metal ions such as Cu, Fe, Zn, Ni, Cd, As, Pb, Cr, etc. Cd exposure was analyzed in the cyanobacterium Nostoc muscorum Meg 1 isolated from a contaminated rice field in Sohra, Meghalaya, India. Toxicity study established 0.5 ppm on day 3 to be the L...
