| Summary: | This study was carried out to test the resistant of three different plastics towards biodegradation. Thes plastics are polyvinyl chloride( PVC) and low density polyethylene ( LDPE ) which are used currently in the insulation of cables, and the resin of polyester ( UPE ) Three different types of bacteria ( Staphylococcus , Pseudo aeraginosa Escheriohia coil )were planted on plastics in different soils of Anbar (Saqlawiyeh , ramadi , Qaeim ) . The biodegradation was followed via the decreace in the overall weight and the molecular weight due to the chains scision and the shift in the functional groups using ( FT– IR) and( I.R, UV), and the depression in the viscosities . Microscope was also use to follow the surface corrosion . The result obtaind indicate that the pvc give the highest resistant tawards biodegradation , and the resistant of the three plastics follow the sequencep;- ( PVC > UPE > PE) .The nature of the soil had also not played a role in the stability of the plastics useds in this research. |
