Antimony, Arsenic and Chromium Speciation Studies in Biała Przemsza River (Upper Silesia, Poland) Water by HPLC-ICP-MS

Abstract

In this paper the total concentration of As, Cr, Sb, pH and the red-ox potential of water and sediment samples of the Biała Przemsza River were determined. The arsenic (AB, MMA, DMA, As(III), As(V)), chromium (Cr(III), Cr(VI)) and antimony (Sb(III), Sb(V)) forms were studied by HPLC-ICP-MS. Ions were successfully separated on Hamilton PRP-X100: (AB, MMA, DMA, As(III), As(V)), Dionex Ion Pac AS-7 (Sb(III), Sb(V)) and Dionex IonPac AG7 columns: Cr(III), Cr(VI) with LOD 0.16 μg/L, 0.08 μg/L, 0.09 μg/L, 0.012 μg/L, 0.08 μg/L, 0.12 μg/L, 0.009 μg/L, 0.012 μg/L, 0.19 μg/L, 0.37 μg/L, respectively. The simplified BCR three-step sequential chemical extraction was performed on the bottom sediment samples. The samples were collected monthly, between April and December 2014, at five sampling points. Large contents of manganese, lead, cadmium and zinc were found in the Biała Przemsza River water. In December 2014, the lead content in the bottom sediment in Sławków was nearly 6000 mg/kg. In the river water, only the inorganic arsenic speciation forms were found. Sb(V), As(V) and Cr(III) were dominant. Studies have shown that arsenic, antimony and chromium were mainly bound to oxides, organic matter and sulphides in the bottom sediments.

Impact of the Pb and Zn ore mining industry on the pollution of the Biała Przemsza River, Poland

“…A slightly higher one was observed at BP1 in Chrząstowice (about 100 μg/L). It increased until December 2014, when it reached 326 μg/L at BP5 (Sosnowiec) (Jabłońska-Czapla 2015 ). Due to the total Mn content in the Biała Przemsza River water, it can be classified within classes II and below II of the surface water quality.…”

“…The sequential chemical extraction also demonstrated that arsenic and chromium were bound to the oxide and sulfide and organic matter fractions in the Biała Przemsza River bottom sediments. At BP1, arsenic was mainly bound to oxides in all seasons (Jabłońska-Czapla 2015 ). For antimony, there were seasonal changes in the ion exchange fraction percentage.…”

“…The ICP-MS Elan 6100 DRC-e (Perkin Elmer, USA) spectrometer was used. The apparatus equipment and optimalization was carried out as in previous study (Jabłońska-Czapla 2015 ).…”

“…Additionally, the way and form in which Mn and other metals were bound in the bottom sediments were determined with the simplified BCR three-step sequential chemical extraction (Tokalioglu et al 2003 ). The extraction procedure conditions are given in previous work (Jabłońska-Czapla 2015 ).…”

Complexation of Antimony with Natural Organic Matter: Performance Evaluation during Coagulation-Flocculation Process

“…The NOM bound Sb was determined by calculating the difference between total and free Sb. The detailed procedure can be found elsewhere [30]. The elemental compositions of the studied HA, SA, and L-cysteine were determined using an elemental analyzer (Vario EL III, Elementar, Langenselbold, Hesse, Germany).…”
