Acid-activated Nibo clay was applied as an adsorbent in the bleaching of crude palm oil. The collected sample activated with hydrochloric acid solution after it sun-dried and ground. raw (NC) (ANC) samples were characterized using XRF, SEM, FTIR analyses. efficiency process examined by varying dosage, temperature contact time. results analyses on NC ANC showed that clays kaolinites significant ...

Soot was harvested from five combustion sources: a dodecane flame, marine and bus diesel engines, a wood stove, and an oil furnace. The soots ranged from 20% to 90% carbon by weight and molar C/H ratios from 1 to 7, the latter suggesting a highly condensed aromatic structure. Total surface areas (by nitrogen adsorption using the Brunauer Emmett Teller, BET method) ranged from 1 to 85 m2 g(-1). ...

Methylene blue dye (MB dye) is a harmful contaminant for wastewater streams of industries and to human aquatic life. An ecofriendly sugar templating process was used generate porous bentonite/polydimethylsiloxane (PB) magnetite nanoparticles/bentonite/polydimethylsiloxane (PBNP) composite absorbents remove MB in this study. During the infiltration PDMS solution into template vacuum chamber, ben...

abstract background: at present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of reactive black 5 (rb5) dye from aqueous environments. materials and methods: the effect of various operating parameters such as ph of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. results: maximum adsorption capacity of ...

the adsorption characteristics of riboflavin onto silver-deposited iron oxide magnetic nanoparticles (ag/fe3o4) have been described. characterization of the synthesized ag/fe3o4 nanoparticles was achieved by ftir spectra, tem image and xrd pattern. the influence of several experimental parameters such as nanoparticles dosage, ph of the sample solution, different orientations of the riboflavin m...

background : hexavalent chromium ( cr (vi)) is an important contaminant in surface and groundwater and its removal from contaminated water and wastewater has received interest in recent years. this study aimed to explain the removal process of cr (vi) from aqueous solution using nano hydroxyapatite (n-hap) as an adsorbent material. methods: cr (vi) removal experiments with the prepared n-hap we...

Herein, mesoporous magnetic nanocomposite (Fe3O4@SBTCA) was specifically designed and fabricated for its high efficient application in the removal of toxic Cd(II) ions from aquatic environment. The structure, surface characteristics, composition nanocomposites were characterized by FT-IR, BET analysis, XRD, TEM, EDX, Zeta potential measurement TGA analysis. TEM images XRD exhibited average part...

Natural dyes exhibit a low dye uptake when cellulosic fiber dyeing is carried out using conventional water bath process. In this research, cotton fabric was exhaust dyed in microemulsion dyebath containing cacao husk extracts and decamethylcyclopentasiloxane (D5) to achieve higher exhaustion percentage on fiber, which an environmentally beneficial The adsorption behavior of extract D5 system in...

Zeolites are widely used in wastewater and contaminated water refinement due to their great adsorption properties. However, Clinoptilolite (as one type of Zeolites) has a relatively low adsorption capacity at least for arsenic ions. Therefore, in order to increase the adsorption capacity, natural Clinoptilolite was modified with sulfuric acid and various tests were then conducted to determine t...

In this study, two Carbon Molecular Sieves using Pistachio shell (CMS P) and Walnut shell (CMS W) were prepared by a chemical vapor deposition method and used for pressure swing adsorption and separation of CO/H2 and CO/CH4. Adsorption isotherms of gases obtained for both CMS’s. The Dubinin-Radushkevich isotherm model was used for comparing pore volum...
