Qualitative and Quantitative Analysis of Heavy Metal and Mineral of Volcanic Ashmount Sinabung by Using Inductively Coupled Plasma (Icp-Oes)

Author(s): Zul Alfian, Emma Zaidar Nst, M Taufiq

The research to analyze the concentration of heavy metal and mineral of volcanic ash Mount Sinabung after eruption in July-August 2016 by using Inductively Coupled Plasma (ICP-OES) was conducted. Sampling was taken in two village s at surrounding Mount Sinabung, which is in Sigarang-garang and Sukandebi Provinsi Karo Sumatera Utara. Sampling was done by collecting volcanic ash which is located in the area affected farm population eruption of Mount Sinabung. Weighted 5 g of volcanic ash and added 5 ml of concentrated HNO3, after that added aquadest up to 50 ml and then heated for 2 h, cooled and then filtered with Whatmann filter paper. The extract obtained is then analyzed by ICP-OES Variant Liberty. Qualitative analysis of Sinabung volcanic ash was done by using X-ray diffraction (XRD) instrument and has obtained the results which consist of heavy metals and minerals are (Ca, Na) (Al, Si)2 Si2O8; (K, Ca, Na) (Al, Mg, Fe)2 (Si, Al)4 (OH);Ca Mn+2 Si2O6; PbO; CuO; ZnO. And, measured of concentration of heavy metals by using Inductively Coupled Plasma (ICP-OES) method, the results were Fe ± 136.5710 ppm, Mn ± 1.0799 ppm, Zn ± 0.2187 ppm, Pb ± 0.0120 ppm, Ca ± 36.3112 ppm, Al ± 4.7699 ppm, Na ± 4.4322 ppm. The presence of heavy metals, there are Al, Pb, Zn although with little concentration still need special attention, because of the eruption of Mount Sinabung continues over time.
