Application of polyurethane@ salvadora persica composite for detection and removal of acidic and basic dyes from wastewater

A novel, stable and inexpensive biosorbent@ polymer composite was synthesized 
by coupling of the biosorbent (Salvadora persica roots, SPR) with polyhydroxy polyurethane 
foam (PPF). The SPR@ PPF was characterized using different tools. It was clear that the 
surface of SPR@ PPF contained nanocrystals particle dispersed in the amorphous phase 
and also contained 2.4 and 1.0 mmol/g of acidic and basic sites. Thermogravimetric curve 
showed two endothermic peaks at 304 and 396° C due to the cupling of SPR@ PPF. T
