Effects of Internal Surface Area and Window Opening

2 Effects of Internal Surface Area and Window Opening [Pg.427]

Research has shown that a solute with a diameter closer to that of zeolite pore dimension showed higher adsorption (close fit mechanism). An important consideration for applying zeolites in drinking water treatment practice is that their size exclusion and close fit adsorption mechanism makes them effective for the removal of specific solutes. [4]. Because the Si Al ratio allows for tuning of the surface properties and the resultant electrostatic double layer such membranes could also be tuned for specific ion-selective applications, but further work is needed to fully understand the connection between zeolite chemistry and membrane performance. Osewe (2014) investigated the dissipation half-life of malathion as affected by the largest window opening for FAU, MOR, and ZSM-5s zeolites [16]. [Pg.427]

Pendergast and Hoek (2011) report that molecular dynamics simulations showed that zeolite membranes - previously applied solely for gas separations - may be applicable for aqueous osmotic separations. Since [Pg.427]

That zeolites having higher BET surface area showed greater retention for bisphenol A. In addition, the uptake of bisphenol A was improved slightly in the presence of NaCl and was enhanced at a low temperature [2]. Phenols are toxic compoxmd coming from a variety of industrial sources, such as pesticides, dyes, and paper industries, coke and resin manufacturing, textile, plastic, rubber, pharmaceutical, and petroleum production. A study reported that Bisphenol A uptake increased at alkaline pH conditions, which enabled the formation of bisphenolate anion. The preferred [Pg.428]
