But, they also have a collection of autodosers that can help you automate pH dosing and nutrient delivery for good! Bi, X.M. The two most widely used green metals (antimony and bismuth) were tested for the in situ formation of the metallic film on the working electrode [, The effect of the Bi(III) solution concentration used for the in-situ formation of the bismuth film on the stripping peak currents of Pb and Cd is illustrated in, The deposition potential was studied in the range 0.0 to 3.0 V. The stripping signals of both the target metals increased as the deposition potential became more negative and leveled off at 2.5 V which was selected as the deposition potential (, Different stripping modes were investigated for the stripping step (, In this work, a graphite carbon electrode was used as a quasi-reference electrode. The marker pen was inserted into the holder of the plotter and the 24 (4 6) PADs were drawn on the paper using a plotting speed of 0.76 cm s, For CV measurements, 100 L of a 0.002 mol L, For stripping voltammetry measurements, a 160 L aliquot of the sample was spiked with 40 L of the 2.5 mol L, Then, a positive-going potential scan from 1.5 V to 0.2 V was applied in the differential-pulse (DP) mode (scan rate, 10 mV s.
