Figure 6

Percent of total Pb in chloride complexes and hydroxide complexes as a function of pH-log conditions along the 100 ppm total Pb isopleth in Fig. 2. Specific pH-log conditions (pH, log ) are given in Table 4, along with corresponding % of total Pb values for various forms of Pb, and begin at the right end of the 100 ppm isopleth with data set #5 (8, -50.20), followed by #4 (7, -49.95), #3 (5, -49.90), #2 (4, -49.90), and #1 (3, -49.90).
