Dextran sulfate was covalently bound to cellulose beads (LA01) and used as the specific sorbent of apolipoprotein B-containing lipoproteins. The binding profiles of very low density, low density, and high density lipoproteins to the material were consistent with simple Langmuir adsorption isotherms. Although the affinities of all lipoproteins for the sorbent were roughly similar, the surface ar...

Sorption systems are a prevalent technology in the field of environmental engineering for treating waters contaminated with organic and/or inorganic compounds. Examples of such contaminants include taste and odor, hardness, disinfection byproduct precursors, and arsenic. The primary operating costs for these sorption systems lie in sorbent replacement. Different column arrangements and the use ...

Abstract Recently, the adsorption process relied on use of low-cost, available and eco-friendly materials to reduce costs. Pomegranate peels(PPs) have been used as environmental inexpensive bio-sorbent material remove dye (brilliant yellow) from aqueous solution. characterization via two techniques like FTIR, FESEM analyze morphology chemical groups before after sorption brilliant yellow dye, A...

Abstract In this work, laser-induced breakdown spectroscopy (LIBS) was applied to qualitatively evaluate lead adsorbed from industrial wastewater by nano-CaCO 3 . Eggshell as a natural source of CaCO has been used sorbent owing its low cost and unrivalled adsorption capacity remove Pb contaminated water. The structure morphology nano-powders were investigated using scanning electron microscopy ...

In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mg...

there was a turning point in each period of time which human has discovered a new sight about the world and nature order in a way, and then has presented this relation by numeral, artful and industrial language. biourbanism focuses on the urban organism, considering it as a hyper complex system, according to its internal and external dynamics and their mutual interactions. nowadays when it is t...

Almond green hull, an agriculture solid waste, was chemically treated and used for the adsorption of Co (II) from aqueous solutions. The efficiency of this new adsorbent was studied using batch adsorption technique under different experimental conditions such as sorbent amount, initial metal-ion concentration, contact time, adsorbent particle size, and chemical treatment. Optimum dose of sorben...
