Water pollution has become a major issue in many countries, including Malaysia. Malaysia is one of the countries that suffers from this detrimental influence on water resource sustainability. Adsorption been discovered to be cost-effective and efficient method removing contaminants such as pigments, dyes, metal impurities. Many biomass-based adsorbent materials have successfully used for remova...

Interactions of C.I. Basic Blue 3 with potassium humate in aqueous systems were investigated. Both the humic content and dye removal are crucial significance relation to water a desired quality. Dye retention experiments demonstrated that is an exceptionally efficient adsorbent. The effect both pH temperature on adsorption process was proved only slightly influence extent sorption; contrarily, ...

Cauliflower leaf powder (CLP), a biosorbent prepared from seasonal agricultural crop waste material, has been employed as a prospective adsorbent for the removal of a basic dye, methylene blue (MB) from aqueous solution by the batch adsorption method under varying conditions, namely, initial dye concentration, adsorbent dose, solution pH, and temperature. Characterization of the material by FTI...

The effect of hydrogen-ion concentration on the toxicity of various organic and inorganic compounds has been studied by a number of investigators. In general the results have shown that the toxicity of anions is increased by increasing the hydrogen-ion concentration and that of cations is increased by decreasing the hydrogen-ion concentration, provided the reaction does not affect the solubilit...

(a) by competing for hydrogen bonding sites in the tissue or on the dye particle, it may inhibit staining in which the dye-substrate link is a hydrogen bond; (6) because it is a dipole, urea may have some affinity for charged sites in the tissue, and thus tend to reduce electrostatic staining; (c) urea may in some cases decrease staining by increasing the solubility of the dye; (d) by inhibitin...

Carboxymethyl cellulose (CMC)/titanium dioxide (TiO2) was prepared using gamma irradiation at different doses. used as a matrix and TiO2 in contents added (0.25, 0.5, 1, 1.5 wt%) filler. The polymer composite films were irradiated doses of 5, 10 15 kGy 60Co γ-ray to form crosslinked network structure. described by diagnostic procedures including X-ray diffractometer, scanning electron microscop...

In mammals, the part of the nervous system responsible for most circadian behavior can be localized to a pair of structures in the hypothalamus known as the suprachiasmatic nucleus (SCN). Previous studies suggest that the basic mechanism responsible for the generation of these rhythms is intrinsic to individual cells. There is also evidence that the cells within the SCN are coupled to one anoth...

1. Twenty-eight leaf-protein concentrate (LPC) samples, subjected to different thermal treatments, were produced from five curd batches. For these samples, the fluorodinitrobenzene (FDNB)-reactive lysine values gave closer agreement with dye-binding lysine (DBL) than with the dye-binding capacity (DBC). 2. No relationship was established between the dye-bound-after-propionylation (DBAP) and the...

Different liquid phase thermal treatmentswere applied to a commercial activated carbon (Norit ROX 0.8) in order to produce modified activated carbons with varying surface chemistry and increased acidic character. Chemical characterization of the prepared materials includes determination of the point of zero charge and evaluation of the concentration and nature of acidic and basic surface functi...
