The concentration of humic acid was determined by TOC analysis. TOCs for the humic stock solutions were normally 2.3 0.1 g/L. Elemental analysis showed that the powdered humic substance was 52 carbon weight. This result indicates that the theoretical maximum of TOC for an 800-mL solution prepared from 4.0 g of humic substances is 2.6 g/L.

Figure 3. Carbon corrosion rate versus carbon weight loss for both conventional and graphitized KB-supported Pt catalysts. The carbon corrosion rate (in units of A/g( ) is based on the measured CO2 concentration at the exit of a 50 cnr cell using a GC, assuming 4e /( (T molecule. The carbon weight loss is obtained by integrating the measured CO2 evolution rate over time. The cell is operating on neat H2/N2 (95 °C, 80% RIIjn, and 120 kPaa, s) with potential held at 1.2 Volts versus RHE.

Calculation The capacity of a carbon for any adsorbate depends on the concentration of the adsorbate. The concentrations of the standard iodine solution and filtrate must be known to determine an appropriate carbon weight to produce final concentrations agreeing with the definition of iodine number. The amount of sample to be used in the determination is governed by the activity of the sample. If filtrate normalities (C) are not within the range of 0.008 N to 0.040 N, repeat the procedure using different sample weights.
