    Abstract: Natural water is being processed by the Reverse Osmosis purification system in the different area of Bangladesh for drinking purposes. Most of the water processing companies fill the 500 mL, 1000 mL, 2000 mL and 5000 mL bottles with this processed water and sell widely in the different parts of Bangladesh. However, the dissolved minerals in their p... Show More

    Abstract: Herein we report our study on wool dyeing with natural alizarin in a vat system using the Argan’s pulp. Natural alizarin was extracted from the Rubia tinctorum plant using enzymatic hydrolysis and alkaline solution. In order to assess the role of the reducer in the dyeing process, we tested one dye bath without reducer containing just alizarin extr... Show More

    Abstract: In order to prevent of detergent surfactant contamination to water and soil, or even in well water, decreasing surfactant in a laundry wastewater has been studied by using photodegradation under UV/TiO2/H2O2 (photo-Fenton-like) and UV/Fe2+/H2O2 (photo-Fenton) processes. Photodegradation processes were performed in a batch system by exposing UV ligh... Show More

    Abstract: Herein we report our study on the improvement of the Washing fastness of wool dyed with natural alizarin using an alkaline dyeing process. Natural alizarin was extracted from the Rubia tinctorum plant using enzymatic hydrolysis and alkaline solution. The dyeing alkaline process was realized at pH 10 without any mordant. The fastness was clearly hig... Show More

    Abstract: Oxidation of inositol (INOS) by hexachloroplatinate(IV) complex (HCP) in perchlorate solutions in the presence of palladium(II) catalyst was studied spectrophotometrically. The reaction rate was very slow in the absence of the catalyst. The reaction exhibited a first order dependence on [HCP], and fractional-first order dependences with respect to ... Show More

    Abstract: Immersion tests were used to study the inhibition effects of a complex vapor phase inhibitor on rusty iron coins. Electrochemical behaviors of simulated cast iron specimens in corrosion solution with or without inhibitor have been investigated by Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. The rust composi... Show More
