Numerical modeling on streaming field and electroviscous effect in a soft nanochannel is made by considering the finite ion size and ion partitioning effects. The standard electrokinetic model is modified by incorporating the finite ion size effect and the effect of ion partitioning, which arises due to the difference in dielec. permittivity between the electrolyte and wall grafted polyelectrolyte layer (PEL). Such modification in the ion transport equations enable us to consider higher range of wall charge d. as well as higher volumetric charge d. of the PEL. The dielec. permittivity of the PEL may become lower due to the large accumulation of counterions drawn by the PEL immobile charges. The ion steric repulsion is taken into account through the BMCSL (Boublik-Mansoori-Carnahan-Starling-Leland) equation based on the hard-sphere model of ions. This enables to consider different ion sizes, which arise when a mixture of different salts is considered. The governing equations are solved numerically and the streaming field is determined iteratively. We find that the ion steric interactions and ion partitioning effects create a counterion saturation This leads to a reduction in the counterion condensation of the PEL when the PEL and wall are similarly charged, which results in higher streaming field and energy conversion efficiency. The diffuse PEL of pore size in the order of the channel half height creates higher energy efficiency compared to the channel consisting of rigid walls. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Recommanded Product: Lithium chloride).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Recommanded Product: Lithium chloride
