Journal ArticleDOI
Surface modification and characterization of carbonaceous adsorbents for the efficient removal of oil pollutants
Hirra Anjum,Khairiraihanna Johari,Arunagiri Appusamy,Nirmala Gnanasundaram,Murugesan Thanabalan +4 more
TL;DR: Results suggested that the carbonaceous sorbents modified with combination of citric acid tartaric acid, malic acid and salicylic acid showed increased surface area and total pore volume, with the significantly improved thermal stability, compared with other available reported adsorbents.
Journal ArticleDOI
Biosorption of mercury from aqueous solution and oilfield produced water by pristine and sulfur functionalized rice residues
TL;DR: In this paper, the authors presented the biosorption potential of rice residues for Hg(II) removal from aqueous solution and oilfield produced water, where rice husk and rice straw were selected and functionalized with sulfur group from carbon disulfide in alkaline condition.
Journal ArticleDOI
Silver Adsorption Enhancement from Aqueous and Photographic Waste Solutions by Mercerized Coconut Fiber
TL;DR: In this paper, the mercerized coconut fiber (CF-NaOH) was prepared by treating the pristine coconut fiber with NaOH solution, and the morphology and chemical composition of CF-Pure changed after mercerization process.
Journal ArticleDOI
Removal of Mercury (II) from Aqueous Solution by using Rice Residues
TL;DR: In this article, the potential of rice residues for Hg(II) removal from aqueous solution was investigated, and two simple kinetic models, which are pseudo-first-order and pseudo-second-order, were tested to investigate the adsorption mechanisms.
Journal ArticleDOI
High removal performance of dissolved oil from aqueous solution by sorption using fatty acid esterified pineapple leaves as novel sorbents
TL;DR: In this article, the lignocellulosic biomass of pineapple leaves (PALs) was used as an oil sorbent by mercerization and esterification with long chain fatty acids in order to enhance the surface hydrophobicity and thus the oil sorption capacity for the treatment of dissolved oil contaminated wastewater.
