Polymerization of Silica in Water-Effect of Ultrasonic Waves on Coagulation and Sedimentation
Polymerization rates of silica at various concentrations and pHs have been studied via nephelometry. The ability and potency of ultrasonic radiation on the coagulation process in aqueous samples with and without silica colloidal particles have been extensively investigated. Factors affecting the rate and filtration volume such as silica concentration, time of radiation, temperature, and fre...
متن کاملUltrasonic in-line monitoring of styrene miniemulsion polymerization
Ultrasonic transmission is a simple, non-destructive method to characterize turbid systems like e.g. emulsions or polymer dispersion. Here we use this technique for in-line monitoring of the miniemulsion polymerization of styrene. Either the ultrasound attenuation or the velocity signal provides a fingerprint characterizing the reaction process. During the reaction process the sound velocity in...

متن کاملHypolipidemic effect of polyvinylpyrrolidone in man.
Intravenous infusion of 500 ml of 6% polyvinylpyrrolidone (PVP, average molecular weight 40,000) in isotonic saline solution daily for 2 days induced prompt and significant reductions in serum cholesterol and triglyceride concentrations in eight hyperlipidemic patients. Mean maximal decrements in serum cholesterol and triglyceride were 29% and 28% below control values, respectively, occurring 5...
