Disinfection of water with new chitosan-modified hybrid clay composite adsorbent
Hybrid clay composites were prepared from Kaolinite clay and Carica papaya seeds via modification with chitosan, Alum, NaOH, and ZnCl2 in different ratios, using solvothermal and surface modification techniques. Several composite adsorbents were prepared, and the most efficient of them for the removal of gram negative enteric bacteria was the hybrid clay composite that was surface-modified with...
متن کاملRemoval of Cd(II) ions from contaminated water by a new modified magnetic chitosan nano composite
Magnetic chitosan nanocomposites are one of the more recent advanced groups of adsorbents used to remove contaminants from waste water. In this research, N- Nicotinyl-N', N"-bis (Hexamethylenyl) phosphoric triamide (HE) was used as an additive to form a new nanocomposite with the structure of chitosan / 5% Fe3O4 Nps/10% HE resulting in the highly efficient removal of Cd(II...
متن کاملRemoval of microcystin-LR from drinking water using a bamboo-based charcoal adsorbent modified with chitosan.
A new kind of low-cost syntactic adsorbent from bamboo charcoal and chitosan was developed for the removal of microcystin-LR from drinking water. Removal efficiency was higher for the syntactic adsorbent when the amount of bamboo charcoal was increased. The optimum dose ratio of bamboo charcoal to chitosan was 6:4, and the optimum amount was 15 mg/L; equilibrium time was 6 hr. The adsorption is...
متن کاملpeat water treatment using chitosan-silica composite as an adsorbent
the objective of this study is synthesis and characterization of the chitosan-silica composite (csc) and use them as an adsorbent material for peat water treatment. the resulting composite was characterizedby fourier transform infrared (ftir) spectroscopy, scanning electron microscope (sem), x-ray diffraction(xrd), n2 adsorption-desorption isotherm and zeta potential. the sorption experiments w...
متن کاملA new silver based composite material for SPA water disinfection.
A new composite material based on alumina (Al2O3) modified by two surface nanocoatings - titanium dioxide (TiO2) and silver (Ag) - was studied for spa water disinfection. Regarding the most common microorganisms in bathing waters, two non-pathogenic bacteria Escherichia coli (Gram-negative) and Staphylococcus epidermidis (Gram positive) were selected as surrogates for bacterial contamination. T...
