A Comparative Study of the Performance of Polyaluminum
PAC-SA showed a higher removal efficiency of colloidal suspension than PAC-CTS due to alginate’s high viscosity, which improves coagulation via bridging and interparticle entrapment phenomena. The present work highlighted the effect of polyelectrolyte viscosity and aluminum speciation on improving coagulation performance to define promising,lowest cost of nonionic polyacrylamide refractive index Materials for High and Low Refractive Index Coatings. Introduction. Refractive index (RI or n) is of critical importance for photonics applications such as optical waveguides and ophthalmic devices.Based on their unique refractive index characteristics and good optical clarity, polymeric materials are also used as anti-reflective coatings for solar cells, displays and contact lenses. 1,2 With
