Abstract Oil contaminated wastewater is one of serious pollutants that may affect the quality of life for humans and other creatures due its improper ways of disposal. This research work reports new approach during the synthesis of developed polymer-based structures for use in purification of a wastewater samples from petroleum oil via adsorption. Specifically, different grades of polystyrene that were prepared by high internal polymerization technique are presented in this study. The impact of preparation parameters; namely dosing and mixing times, on the efficiency of such polymer grades toward oil removal from the wastewater was investigated. It was detected that the obtained polymer at dosing and mixing times of 20 and 120 min respectively had attained the highest oil removal percentage. Numerically, this polystyrene structure was capable to remove nearly 92 % of existing oil in the introduced wastewater sample. The formerly reported preparation conditions were also utilized to subsequently prepare three core-shell structures. The core of these composites was made of different percentages of freshly synthesized nanoparticles of silica (Sonication of nano silica on aqueous phase) which were then shelled by polystyrene. The composite which contained a silica percentage of 5 % could efficiently remove about 88.67 % of the emulsified oil in the wastewater sample. The attained oil removal by either the blank polymer or its corresponding composite was performed at room temperature and lasted for an operating time of 30 min. |
