SUPPORTING SCIENTIFIC INFORMATION ON POLYACRYLAMIDE (PAAG) HYDROGEL
A biodegradable semi-interpenetrating hydrogel network (semi-IPN) of polyacrylamide and gelatin was prepared using polycaprolactone diacrylate (mol. wt ó 640) as a crosslinker. The drug-polymer interaction and IPN formation were investigated
Results and discussion The synthetic procedure of the multifunctional polymer nanomedicine is presented in Figure 1a.Amine functionalized polyacrylamide (AFPAA) PS conjugated NPs were prepared by using a modified water-in-oil micro-emulsion meth

Polyacrylamide (PAM) cryogels were synthesized by the free radical polymerization of acrylamide using a modified freezing polymerization method crosslinked by CSO-g-AA. The obtained cryogels were macroporous hydrogels which could be degraded
- Can electroplating be used to remove copper and chromium from wastewater?
- In the present study an Electroplating unit employing chrome and bronze plating was selected for process evaluation, removal of copper and chromium from wastewater and exploring the scope of recycling. The chemical treatment was planned to be replaced by physico-chemical process like adsorption.
- Can UV/sulfite treat chrome plating wastewater?
- Specifically, a chrome plating wastewater containing F–53B was effectively treated by UV/sulfite, achieving its entire degradation within 1 h. Comparison with experiments in controlled conditions suggested that the degradation of F–53B is obtainable.
- How chromium is used in electroplating?
- Electroplating is among the industries in which chromium is used widely. Chrome plating can be achieved by using salts of both trivalent and hexavalent chromium oxidation states. The main component in hard chrome plating solution is chromic oxide (CrO3) dissolved in water .
- How to remove CMS from chrome plating wastewater?
- UV/sulfite system is ideal for treating chrome plating wastewater. In fact, sulfite is already utilized in many plants to reduce hexavalent chromium to Cr (III). The employment of a UV irradiating reactor to the sulfite addition section would be the most practicable and economic method to remove also CMS.
