Transport studies of nickel arsenate membrane

Preparation, characterization, biological activity, and transport study of polystyrene based calcium–barium phosphate composite membrane

“…In case of most of the transport measurements, only the membrane water content at saturation is needed, and that too mostly as a function of solute concentration. Thus, low order of water content, swelling and porosity with less thickness of membrane suggest that interstices are negligible and diffusion across the membrane would occur mainly through exchange sites [20].…”

Electrochemical characterization and transport properties of polyvinyl chloride based carboxymethyl cellulose Ce(IV) molybdophosphate composite cation exchange membrane

“…In case of most of the transport measurements, only the membrane water content at saturation is needed, and that too mostly as a function of solute concentration. Thus, low order of water content, swelling and porosity with less thickness of membrane suggests that interstices are negligible and diffusion across the membrane would occur mainly through exchange sites [16].…”

“…These parameters include membrane water content, porosity, thickness and swelling etc. These were determined in accordance with the method as reported in literature and studied by Arfin and Rafiuddin [15,16].…”

“…Swelling was measured in accordance with the procedure described by Arfin and Rafiuddin [16]. It was calculated as the difference between the average thickness of the membrane equilibrated with 1 M NaCl for 24 h and the dry membrane.…”

Impedance characteristics and electrical double-layer capacitance of composite polystyrene–cobalt–arsenate membrane

“…Following this, the polystyrene-doped composite membrane was prepared by the procedure as described by Arfin and Rafiuddin [13][14][15]. Accordingly, the Co-As precipitate was mixed with polystyrene (PS) granules of size less than 200 mesh and pressed under a pressure of 5 ton/cm 2 at 200 8C.…”
