Geotechnical Problems with Pyritic Rock and Soil

2. The sulfur dioxide (SO2) released through combustion can be measured in several ways. Using a LECO Induction Furnace with Automatic Sulfur Titrator (LECO Corp., St. Joseph, MI), the SO2 is collected in a 0.2M hydrochloric acid solution containing potassium, iodine, starch, and a small amount of potassium iodate. 3.
