The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...

In this study, the adsorption of mercury ions by Sargassum bevanom (S. bevanom) by batch method was investigated. The optimum operating parameters such adsorbent dosage, contact time, and pH, were obtained as: a biomass dose of 0.4 g in 100 ml of mercury solution, contact time of 90 mins and pH 7, respectively. Three equations Morris –Weber, Lagergren and pseudo second order are tested to verif...

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

In this current study, aminated graphene oxide (AGO) doped on alginate (Alg) matrix offers AGO@Alg hybrid spheres was developed to investigate its potential for retention of fluoride from water. The sophisticated characterization methods likely TGA, SEM, XPS and FTIR studies were attained recognize physicochemical properties like thermal stability, morphology, elemental binding energy functiona...

In this study, we used a novel composite material based on magnesium phosphate cement (MPC) to explore the retention of fluoride from water. Dead-burned oxide (MgO), ammonium dihydrogen (NH4H2PO4), and few retarders were create particular substance. Several studies have corroborated performance using aluminum in capture fluoride. From perspective, attempted reinforce our matrix with different q...

In the present study, CoAl-NO3 Layered Double Hydroxides (CoAl-NO3-LDH) was synthesized and an enolate anion of 4-Aminoacetophenone (AAP) intercalated into LDH following reconstruction approach. The CoAl-NO3-LDH CoAl-AAP-LDH were characterized by Fourier-Transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) energy dispersive (EDX) analyses. worked ...

Understanding methane adsorption behavior on deep shales is crucial for estimating the original gas in place and enhancing recovery shale formations. In this study, within lower Silurian Longmaxi formation from Sichuan Basin, South China was conducted at pressures up to 50 MPa. The effects of total organic carbon (TOC), temperatures, clay minerals, moisture content capacity were discussed. resu...

This study aims to prepare a novel adsorbent containing cellulose nanocrystals (CNC) isolated from date pits (DP) and ionic liquid (IL). The prepared composite of CNC IL was then loaded onto the DP [email protected] adsorbent. boron remediation capability investigated using compared that DP. results showed superior performance as maximum adsorption capacity 97 mg/g 69 obtained with DP, respecti...

Chromium (Cr) in water bodies is considered as a major environmental issue around the world. In present study, aqueous Cr(VI) adsorption onto rice husk was studied function of various parameters. Equilibrium time achieved 2 h and maximum 78.6% at pH 5.2 120 mg L−1 initial concentration. isotherm experiments, sorption observed 379.63 g−1. Among four models, Dubinin–Radushkevich Langmuir models s...

Interactions between polyphenols and dietary fiber might play an important role in <br /> polyphenol bioactivities. These interactions can be studied through adsorption processes. The aim of this study was to investigate the phenolic acids (p-coumaric acid, caffeic chlorogenic acid) onto – β-glucan. Adsorption carried out at different temperatures (25, 37, 45 °C) pH values (1.5, 5.5, 10)....
