Linear and crosslinked Polyurethanes based catalysts for reduction of methylene blue
The large amount of synthetic dyes in effluents is a serious concern to be addressed. The
chemical reduction is one of the potential way to resolve this problem. In this study, linear
and crosslinked polyurethanes ie LPUR & CLPUR were synthesized from toluene
diisocyanate (TDI), polyethylene glycol (PEG; 1000 g/mole) and tetraethylenepentamine
(TEPA). The structure and morphology of synthesized materials were examined by FTIR,
SEM and BET. The CLPUR was found stable in aqueous system with 0.80 g/cm 3 density …
