<p>The purpose of this work was to determinate the amount of titanium in different environmental water samples spiked with crop biostimulant Tytanit. The measurements were conducted using adsorptive stripping voltammetry (AdSV). The titanium complex with chloranilic acid was accumulated on mercury film silver based electrode (Hg(Ag)FE) at the potential -0.3 V. The analysis of natural water samples enriched with Tytanit, collected in the eastern part ofPolandconfirms that this procedure is fast and essential for the determination of titanium in environmental water samples.</p>

 ABSTRACT Study of optimation chromium (VI) in sea water by adsorptive stripping voltammetry has been done. The aim of this method to get optimum conditions for determination of Cr(VI). Adsorptive stripping voltammetry (AdSV) has been used for the ultra trace determination of chromium using 2,2’- bipyridin as ligand. Parameters were done, like accumulation time, concentration of ligand, pH, accumulation potential, electrolyte concentration and catalyst concentration. In this case, the optimum conditions were reached in accumulation time 80 second, pH 5.0, concentration of 2,2’- bipyridin 10 μM, accumulation potential -0,6 Volt and electrolyte concentration (NH4Cl) 0,1 M. In the optimum conditions, a linear calibration graph was obtained with correlation coefficient of 0.9971, the relative standard deviation was 15.06 % for eight replicates (n = 8) measurements of 10 μg/L of Cr(VI). The detection limit method was 0.1692 μg/L. The method was applied to the direct determination of Cr(VI) in sea water around Muara Padang water. Concentration Cr(VI) in sample was equal to 0.9684 μg/L with recovery of 90.23 %. Keywords : optimation, chromium, adsorptive, stripping, voltammetry
