摘要：

The water oxygenation constitutes an important factor in the development of self-purification phenomenon in rivers. The replenishment of dissolved oxygen in water can be represented by the reaeration coefficient (K-2). This work was used propane contained in the GLP as tracer in reaeration tests. The tests showed that the use of LPG is feasible, both from analytical point of view, as of the economic. From an analytical standpoint, the results were comparable and even superior to the traditional technique of tracer gas. From an economic standpoint, the cost to perform each test has been reduced.
