WebBoth filters performed with efficient solvent clearance and track a theoretical process in which no retention of the solvent by the membrane is assumed, calculated using a sieving coefficient (S) of 1. The decrease in DMSO removal rate after ~8 diavolumes may be due to the presence of dead legs in the system and charge interactions. WebA series of sieving coefficients is available that allows calculation of the amount of drug actually lost if the ultrafiltration flow rate is known. 5 The sieving coefficient is the ratio of …

WebA useful tool to predict the likelihood of a drug to cross the hemofilter membrane is the sieving coefficient. This term is defined as the ratio of drug concentration in the ultrafiltrate to the pre- filter plasma water concentration of the drug. If the sieving coefficient is close to 1.0, the drug has relatively free passage across the filter. WebLithium ion sieve (LIS) has attracted great attention due to its high adsorption selectivity towards Li +.Herein, a new type of Zr-doped Ti-LIS (HZrTO) was synthesized by a simple calcination method. The adsorption capacity increased from 56.3 mg g −1 (before doping) to 93.2 mg g −1 after doping in LiOH solution (lithium 1.8 g L −1).The adsorption isotherm …
