Abstract
Ritual practices in religion were generally studied in social science contexts. However, soil dust (SD) as a material for cleaning ritually unclean substances in Islamic teaching attracts attention in the chemical science context. Substantially, unclean substances are sourced more from organic matters (OM) than inorganic matters. This study objected to understand the purity practices of Muslims using SD that correlated with the levels of Si, Al, Fe, and Ca in adsorbing methylene blue as a representation of unclean substance and CuSO4 as a non-unclean substance. This study included experiments with SDs (0.02 g) that was contacted with MB (10 mL, 50 ppm) and CuSO4 (20 mL, 100 ppm as Cu2+) solutions with stirring for 2 minutes at room temperature. The experiment conditions, MB and Cu2+ were adsorbed in the range 70.9 – 97.37% and 45.43 – 73.53%, respectively. Using the contact time, the range of adsorption capacities of SD samples was 7.09 – 9.74 and 50.88 – 73.04 mg per g of SD, respectively. The power adsorption of SD against MB and CuSO4 tend to be influenced by the content of the mentioned elements. In addition, the calcination treatment decreased the percentage of adsorbed MB and CuSO4 so that the OM content in soil dust has a direct role in its adsorption power. From the results, the practice of ritual purity of Muslims using soil dust can be explained through the adsorption mechanism which is directly influenced by the chemical nature of the soil dust.
