Amygdalus persica L., belongs to Rosaceae family, and its flowers are used as medicine food. n-Butanol extract of A. were isolated purified with various column chromatographies, the fourteen compounds, chlorogenic acid butyl ester (1), rutin (2), protocatechuic (3), caffeic (4), 5-O-coumarroylquinic methyl (5), kaempferol-3-O-neohesperidoside (6), quercetin-3-O-β-D-glucoside (7), 3,5-dicaffeoyl...
[1] This paper describes new and modified numerical techniques for solving the sizeand time-dependent aerosol processes of nucleation, coagulation, condensation, dissolution, and reversible chemistry among multiple aerosol particle size distributions and the gas phase and over the entire relative humidity (RH) range. The techniques treat particle number, mole, and volume concentrations, solutio...
Background and Objectives: wastwaters of textile industries contain large amounts of color can create a lot of pollution. There are different methods for decolorization of textile industries, for example the methods of coagulation, floocculation, chemical oxidation, biological treatment, electrochemical techniques, including ion exchange and other processes. The purpose of this study was to com...
Pathogen reduction is a viable approach to ensure the continued safety of the blood supply against emerging pathogens. However, the currently licensed pathogen reduction techniques are ineffective against non-enveloped viruses such as hepatitis A virus, and they introduce chemicals with concerns of side effects which prevent their widespread use. In this report, we demonstrate the inactivation ...
The widespread use of reagent coagulation in the technology purification natural and waste waters is due to complexity chemical composition phase-dispersed state aqua systems these waters, on one hand, multifactorial action coagulants them, other. mechanisms interaction between pollutants wastewater which are different states include physicochemical phenomena coagulation, heterocoagulation, ada...
Background and Objectives: Wastewater treatment of paper recycling and cardboard industries with the aim of water recycling and reducing environmental impact is one of the daily needs of industries. Therefore, the aim of the present study was to optimize the conditions of coagulation and flocculation process in wastewater treatment of paper recycling industries using the response surface method...
