Can polyacrylamide hydrogels be swollen in aqueous calcium chloride solutions?

To this end, the swelling procedure of polyacrylamide hydrogels in aqueous calcium chloride solutions is optimized. The achievable salt loading in the hydrogel is characterized as a function of temperature, calcium chloride concentration in the swelling solution, and the hydrogel preparation conditions.

What is polyacrylamide hydrogel?

.acrylamides have alkyl or hydroxy alkyl groups (Ghanshyam et al., (2000).. Polyacrylamide hydrogel is an atoxic, stable, nonresorbable sterile watery gel consist ng of approximately 2.5% cross-linked polyacrylamide and nonpyrogenic water. Polyacrylamide hydrogel is widely used in ophthalmi o

How is polyacrylamide based hydrogel prepared by scanning electron microscopy?

Can cellulose/polyacrylamide composite hydrogel be used to treat heavy metal ions?

C.B. Godiya et al., Carboxymethyl cellulose/polyacrylamide composite hydrogel for cascaded treatment/reuse of heavy metal ions in wastewater. J.

Does carboxymethyl cellulose polyacrylamide remove cationic dye?

Aljeboree, A.M., Ghazi, H.H., Hussein, S.A. et al. Facile fabrication of a low-cost carboxymethyl cellulose–polyacrylamide composite for the highly efficient removal of cationic dye: optimization, kinetic and reusability.

Can polyacrylamide sorbent materials be scaled-up?

In addition, it is critical to note that the combination of materials used in this work are remarkably well-suited for scaled-up production of sorbent materials, as polyacrylamide is simple to synthesize in large quantities and the addition of CaCl 2 to the polymer matrix is straightforward and done by soaking the hydrogels in solution.
