Studies in Ultrafiltration
We are submitting this series of experiments as observed facts, realizing that there are so many uncertainties in this form of indirect observation that great caution must be exercised in drawing conclusions of any kind. The most serious of the possible errors involved is that the active substances which we have studied, the enzyme-the bacteriophage-and the several varieties of virus, may not b...
متن کاملBalanced ultrafiltration, modified ultrafiltration, and balanced ultrafiltration with modified ultrafiltration in pediatric cardiopulmonary bypass.
This study evaluates the effect of balanced ultrafiltration, modified ultrafiltration, and balanced ultrafiltration with modified ultrafiltration on inflammatory mediators in children's open-heart surgery. Eighty children with congenital heart disease were randomly divided into four groups: control group (C group); balanced ultrafiltration group (BUF group); modified ultrafiltration group (MUF ...
متن کاملPreparation, Characterization and Application Studies of PVDF- PS Ultrafiltration Membranes
Polyvinyledenefluoride–polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion technique. Casting solutions were prepared with different compositions of polyvinylidene fluoride (PVDF) and polystyrene (PS) both in the presence and absence of the additive, polyvinylpyrolidone (PVP) using dimethylacetamide as solvent. The effects of compositions of PS and concentr...
متن کاملUltrafiltration I. Ultrafiltration of Electrolytes from Alkali
Ultrafiltration is an important research tool in colloid chemical and in certain types of biological investigation. However, in spite of the many years that ultrafiltration has been used as a research tool, the phase of the subject concerning the ultrafiltra tion of electrolytes from systems containing electrically charged colloids has been lacking in both experimental data and a theoretical ba...
متن کاملA Review of Studies on Micellar Enhanced Ultrafiltration for Heavy Metals Removal from Wastewater
Micellar enhanced ultrafiltration (MEUF) process has been used for the removal of copper, chromate, zinc, nickel, cadmium, serinium, arsenate and organics like phenol, o-cresol. This paper reviews various factors such as operating pressure, surfactant concentration, pH of solution, temperature, presence of non-ionic surfactant and salt, membrane type and its pore size and some inhibiting additi...
