Sorbent materials based on a hydrazone Schiff base compound, C(14)H(11)BrN(4)O(4), were prepared either by immobilizing the ligand into sol-gel (SG1) or bonding to silica (SG2). The sorbent materials were characterized by FT-IR, EDX, SEM, TEM, and TGA. The sorption characteristics of a matrix of eight transition metal ions (Ag(+), Cu(2+), Co(2+), Ni(2+), Fe(3+), Pb(2+), Zn(2+), and Mn(2+)) usin...

The aim of this work is to develop a preconcentration procedure of Cd(2+), Zn(2+) and Cu(2+) in environmental waters using olive pomace (OP) prior to their determination by flame atomic absorption spectrometry (FAAS). Raw OP as preconcentrating sorbent was found to have low permeability towards the passed water samples and thus long time was needed. Even reducing the vacuum pressure caused cart...

Integrated gasification combined cycle with CO 2 capture and sequestration (IGCC-CCS) emerges as one of the most promising technologies for reducing CO 2 emission from coal power plant without reducing thermal efficiency significantly. However the high capital cost of these plants has limited their deployment. The current solvent-based low-temperature CO 2 capture process (Selexol process) is e...

Interaction between electric charges is an important factor in protein adsorption. Similar charge signs on the protein and the sorbent surface opposes adsorption, but whether it prevents ad.: sorption depends on other factors such as dehydration of the protein and the sorbent and structural rearrangements in the protein molecule. Ribonuclease, that does not strongly change its structure upon ad...

A magnetic sorbent with stable and superior magnetic behaviour was developed for His-tagged protein purification by immobilized metal affinity chromatography (IMAC). Magnetic, monodisperse and porous silica microspheres 6 mm in size, with bimodal pore size distribution including both mesoporous and macroporous compartments were synthesized as the base material by a staged-shape template hydroly...

The investigation of the characterization Adansonia digitata biomass from pyrolysis in a fixed-bed tubular carbon steel reactor at temperatures 400℃ to 700℃. Firstly, proximate, ultimate, and heating value analyses raw were obtained prior experimental runs via fast process; thereafter, quality bio-oil biochar yields for bioenergy industrial applications was investigated using following analyses...

Development of bio-based sorbents (i.e., chitosan moieties) at nanoscale size for the removal metal contaminants is main target this research. Grafting with thiazole heterocyclic derivative gives fast kinetics sorption, highly loading, and good recyclability mining leaching solution. Different analyses tools including (thermogravimetric analysis (TGA), scanning electron microscope energy disper...

Sorbent material based on a novel thiosemicarbazone compound, C H N S, was prepared by 12 18 4 immobilizing the ligand into gel matrix (SG). The SG sorbent was characterized by FT-IR, EDX, SEM, TEM and TGA. The competitive sorption characteristics of eight transition metal ions (Ag , Cu , Co , Ni , Fe , Pb , Zn + 2+ 2+ + 3+ 2+ 2+ and Mn ) using batch method was studied using atomic absorption s...
