Remote Sampler for Determining Residual Oil Contents of Surface Waters

Résumé du livre

A sample flow-through device has been developed which, in conjunction with a skimmer and pump, can process 100 to 200 liters or more of surface water, removing any oil present in a separate phase. Thus concentrated, the oil can be extracted at a laboratory, its quantity and nature determined, and when related to the volume of water processed through the sampler, provide oil concentration data on a time integrated basis. Key to the development of this device was identification of a sorbent material which would quantitatively remove oil from a moving water stream and permit simple extraction of that oil in a laboratory. A number of sorbent materials were examined with this apparatus and several were found effective. (Modified author abstract).
