Study on the efficacy of mineral wool wastes in adsorption of waterborne oil contamination (Kerosene)

Abstract

Background and aim: water oil contamination has occurred in Iran since the previous century and environmental oil accumulation threatens the country water resources’ health. There are several methods to remove oil and its derivatives contamination. In the present study, mineral wool waste was used as low price adsorbent for wastewater oil contamination (kerosene) removal. Materials and methods: first, XRF and XRD analyses were used to determine chemical composition. Then, adsorption tests were conducted discontinuously using laboratory solutions containing oil to determine optimum adsorption conditions by adjustment of effective factors such as pH, initial concentration, exposure time and adsorbent concentration. Thereafter, application of adsorbent for laboratory wastewater was studied. Results: after 15 min exposure, the adsorbent (mineral wool wastes) efficacy was significantly higher than the other times (76.01 % adsorption; P
