In the determination of chlorine in petroleum products by microcoulometric procedure, the influences by nitrogen, sulfur, and phosphorus compounds which often exist in the petroleum products were observed. These interferences were eliminated quite successfully by setting the scrubber tube packed with the cupric oxide wire after the combustion furnace. This accelerates complete combustion of the sample and prevents introduction of the phosphate into the cell by absorption. Several samples, e.g., hydraulic fluid (phosphate ester fluid), were analyzed by this method and the results compared with those from some other methods. 5 figures, 4 tables.
