Latest Patents

Kailasam holds a patent for "Nanoporous silica polyamine composites with surface-bound zirconium (IV) and methods of use." This patent describes silica polyamine composites (SPC) made from silanized amorphous nano-porous silica gel and poly(allylamine) (BP-1). The composites were functionalized with phosphorus acid using the Mannich reaction, resulting in a phosphonic acid modified composite (BPAP). Zirconium (IV) was immobilized on BPAP, allowing for strong adsorption of arsenate anions in a pH range of 2 to 8, while arsenite showed good adsorption only at pH 10. The resin was successfully regenerated for As(V) and As(III) using 2M-HSO, demonstrating its effectiveness over multiple cycles.
