Removal of malachite green from dye wastewater using neem sawdust by adsorption.
S.D. Khattri,M.K. Singh +1 more
TL;DR: The adsorption of dye on neem sawdust was found to follow a gradual process and the dimensionless factor, R(L) of the malachite green, neemsawdust isotherm revealed that the adsorptive process is favourable in nature.
Journal ArticleDOI
Quaternized magnetic microspheres for the efficient removal of reactive dyes
TL;DR: This work provides a reusable efficient adsorbent for the removal of RDs and the Langmuir equation and the Freundlich model fit the isotherm data for OG and RWO adsorption, respectively.
Journal ArticleDOI
Magnetic nanoparticles coated by aminoguanidine for selective adsorption of acid dyes from aqueous solution
TL;DR: Magnetic nanoparticles modified with aminoguanidine (AG) were synthesized and characterized with transmission electron microscopy (TEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and infra-red spectra (IR) as mentioned in this paper.
Journal ArticleDOI
The removal of anionic dyes from aqueous solutions in the presence of anionic surfactant using aminopropylsilica--a kinetic study.
TL;DR: It is suggested that the chemical structure of the dye, as well as the presence and position of its sulfonate groups are important factors that affect the anionic dye/SDS aggregations and the adsorption quantities.

Preparation and characterization of surface bond-conjugated TiO2/SiO2 and photocatalysis for azo dyes
TL;DR: In this paper, a surface bond-conjugated TiO2/SiO2 was prepared by means of the impregnation method, which showed three times higher photoactivity for the degradation of reactive 15 (R15) compared to B-TiO2.

Adsorption of dyes onto carbonaceous materials produced from coffee grounds by microwave treatment.
Mizuho Hirata,Naohito Kawasaki,Takeo Nakamura,Kazuoki Matsumoto,Mineaki Kabayama,Takamichi Tamura,Seiki Tanada +6 more
TL;DR: The microwave treatment would be useful for the carbonization of organic wastes to save energy and indicate that the adsorption of dyes depended upon the surface polar groups on the carbonaceous materials.
