Chitin-char is obtained from fast pyrolysis of chitin. To obtain the maximum surface area, chitin-char treated by nitric acid. Then, a kind new arsenic removal bio-material prepared loading Ca(OH)2 on char (called Ca(OH)2-char). IR spectroscopy before and after treatment reveal at least three distinct patterns peak changes. An adsorption study performed different doses, pHs, coexisting ions in ...

As an eco-friendly material, Zn-adeninate bio-metal-organic framework (bio-MOF) was investigated as efficient adsorbent for both anionic and cationic dyes. The adsorption capability of the synthesized bio-MOF confirmed by its notable surface area 52.62 m2 g−1 total pore volume 0.183 cm3 g−1. profiles direct red 81 (DR-81) methylene blue (MB) dyes were under different operating parameters. optim...

The guaiacol adsorption capacity of several Y zeolites with different physicochemical properties was tested by performing breakthrough experiments, in order to investigate the on Fluid Catalytic Cracking catalysts during bio-oils/FCC feedstocks co-processing. X-Ray diffraction, nitrogen sorption measurements and pyridine followed Infrared Spectroscopy were used determine framework Si/Al ratio, ...

Deoxynivalenol (DON) (also called vomitoxin) is a mycotoxin caused by pathogens that periodically contaminate crops such as maize, wheat, barley, oats, and rye, making them unusable. We explored pyrolysis process for the decontamination of vomitoxin-corn grains their transformation into value-added products. Pyrolysis was carried out in bench-scale batch reactor at maximum temperatures between ...

one of the bio-sensing mechanisms is mechanical. rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. this study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on silicon wafer, with the ...

The hydroisomerization of n-alkanes is an important step in the production high-quality bio-aviation kerosene. A SAPO-11 molecular sieve was synthesized using hydrothermal synthesis method, and a 0.5 wt% Pt/SAPO-11 catalyst prepared impregnation method. crystal phase, pore structure, acidity, morphology were characterized via X-ray diffraction, N2 adsorption-desorption, NH3 temperature-programm...

This study, based on circular economy principles and sustainable development practices, aims to present the results of soil samples analysis after their mixture with a biobed bio-mixture straw, compost, used for two consecutive years as organic bio-filter olive oil mill wastewater. So far, exhausted bio-mixtures in biobeds minimize pesticide point-source contamination turned out contain residue...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

in this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. for this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. in other step, aniline monomers and chitosan were polymerized in the presence of iron (iii) chloride to sy...
