| Popis: | The adsorption of crude oil from wastewater on the crosslinked poly(vinyl alcohol) hydrogel (HPVA) and its foam (HPVAF) was reported. The macroporous HPVAF was prepared by adding CaCO3 and epichlorohydrin as pore-forming agent and crosslinker, respectively. The prepared hydrogels were characterized, and their ability to adsorb and immobilize the crude oil was assessed by gravimetric method at the optimum condition. The HPVAF carrier demonstrated the improvement in the hydrocarbon trapping than the HPVA one. Scanning electron microscopy showed the presence of extracellular structures that could play an important role in the immobilization stability of crude oil on polymers. As well, the percentage removal ability of the crude oil by HPVAF was approximately, 82%. The results suggest the potential of using HPVA and HPVAF films as trapping for crude oil to enhance the treatment of oily wastewater with a low cost in an open marine environment. |
