The temperature effect on electrokinetic properties of the silica–polyvinyl alcohol (PVA) system
The influence of polyvinyl alcohol (PVA) adsorption on the structure of the diffuse layer of silica (SiO(2)) in the temperature range 15-35 °C was examined. The microelectrophoresis method was used in the experiments to determine the zeta potential of the solid particles in the absence and presence of the polymer. The adsorption of PVA macromolecules causes the zeta potential decrease in all in...
متن کاملDegradation of Polyvinyl Alcohol (pva) by Fenton Process
Degradation of polyvinyl alcohol was studied a combination of chemical treatment with Fenton process and biological degradation in anaerobic environment. The experiment was based on different amounts of hydrogen peroxide and of Fe(II) added to water solution of PVA of concentration 200-500 mg.L. Fenton process was monitored by analyzing the total organic carbon (TOC) in the solution. Depending ...
متن کاملEffect of Polyvinyl Alcohol (PVA) Containing Artemether in Treatment of Cutaneous Leishmaniasis Caused by Leishmania major in BALB/c Mice
BACKGROUND Polyvinyl alcohol (PVA) is one of the well-known polymers, which has been used in numerous biomedical applications because of its good biocompatibility. OBJECTIVES Due to problems made by the therapeutics already used for leishmaniasis, the aim of this study was to evaluate the effect of PVA containing artemether in treating cutaneous leishmaniasis in BALB/c mice. MATERIALS AND M...
متن کاملImmobilization of activated sludge using improved polyvinyl alcohol (PVA) gel.
The microbial immobilization method using polyvinyl alcohol (PVA) gel as an immobilizing material was improved and used for entrapment of activated sludge. The oxygen uptake rate (OUR) was used to characterize the biological activity of immobilized activated sludge. Three kinds of PVA-immobilized particles of activated sludge, that is, PVA-boric acid beads, PVA-sodium nitrate beads and PVA-orth...
متن کاملPolyvinyl-alcohol (pva)-based Rf Humidity Sensor in Microwave Frequency
A highly sensitive, passive relative humidity (RH) sensor using polyvinyl-alcohol (PVA) dielectric film is presented. For the first time, PVA is investigated in microwave RF sensing devices for low cost, high resolution and accurate chipless RH sensor realization. Comparative study with traditional humidity sensing Kapton polymer is presented to validate superior performance of PVA film. Result...
