Characterization ionic species fine particulate samples in Indonesia by ion chromatography

Abstract

Particulate is one indicator of air pollutants derivative from a complex mixture of large and small particles that are decomposed. Particulate diameter at 2.5 to 100 mm consists of dust originating from agriculture, building construction, and vehicles. Particulates with a diameter of less than 2.5 mm are generally made from fossil fuels and vehicle exhaust containing various specific chemicals or ions. In this activity, characterization of chemical content and specific ions in fine particulates was carried out in fine air particulate samples by ion chromatography. Sampling was carried out in several regions in Indonesia such as Pekanbaru, PalangkaRaya, Manado, Ambon, Jayapura, Denpasar, and Surabaya. The validation methods using reference materials. On the other hand, verification of measurements is carried out regularly with ED-XRF therefore accurate and precise quality can be obtained. The results of this activity obtained several cations and anions such as Ca2+, K+, Mg2+, Na+, SO4 2-, NO3 −, F−, and Cl−. The results obtained from this activity are expected to be used as basic data and scientific-based references for regional/national in formulating, taking appropriate and directed actions and policies to solve the problem of air pollution.
