In this study, polyvinylidene fluoride (PVDF) flat membranes were treated with potassium hydroxide (KOH), sodium hydroxide (NaOH) and sodium hypochlorite (NaOCl). The effects of temperature, treatment duration and chemical concentration towards the properties of PVDF membrane were contrastively studied. Following treatment, membrane became much brittle with a reduced nominal elongation to as lo...
A simple, inexpensive and sensitive three-phase hollow fiber liquid-phase microextraction (HFLPME) coupled with high performance liquid chromatography (HPLC) with UV detection was successfully developed for determination of trace level of an anti-Histamine drug, fexofenadine, in human plasma and urine. The analyte was extracted into n-octanol that was immobilized in the wall of a porous hollow ...
Humidification process is one of the applications of membrane contactor in which partial pressure of a vapor in the gas stream increases. In this study, two different polyethersulfone and polyetherimide hollow fiber membranes were fabricated and characterized by various test methods and their performance in humidification process under different operating conditions was investigated. The PES me...
