Synthetic dye biosorption performance of Prunus laurocerasus L. plant species from wastewater medium: promising candidate for remediation of polluted water environment

Billions of cubic meters of wastewater are generated every year due to human-induced activities, such as indiscriminate release of large amounts of noxious pollutants into water bodies, causing a global crisis in supply of safe and clean water. Biosorption, as a green generation treatment technique using biomass-based materials, has attracted great attention recently. Herein, for the first time, Prunus laurocerasus L. plant species, which is widely available worldwide and has a rich bioactive content, was examined for removal of Basic Red 46 synthetic dye as a target refractory pollutant from wastewater medium. Biosorbent material exhibited a suitable surface morphology with a rich diversity of functional sites for synthetic dye retention. Optimal treatment efficiency was achieved under operating conditions where pH was 8, biosorption time was 120 min, pollutant concentration was 30 mg L−1 and biosorbent dose was 10 mg. Experimental biosorption data showed good fit to pseudo-second-order (Pso) and Freundlich models. Monolayer biosorption capacity of biosorbent was calculated as 86.807 mg g−1. Biosorption process was spontaneous and physical in nature. Overall, this research showed that P. laurocerasus-based biosorbent material could be a promising candidate for remediation of water medium polluted with such refractory pollutants.
