The application of Tenax to the extraction of organic micro-pollutants such as pesticides and polychlorobiphenyls from waters has been studied, and it has been observed that also in the presence of other pollutants (oil, surface-active substances, etc.) the results obtained with an absorption column of Tenax-Celite are equivalent to those obtained with the continuous liquid-liquid extraction technique. For natural waters that contain solids in suspension that adsorb pesticides, it may be necessary to filter the water before extraction with Tenax and then to extract the suspended solids separately. Analyses of river and estuarine sea waters, filtered before extraction, showed the effectiveness of Tenax, and the extracts obtained for the pesticides analysis prove to be much less contaminated by interfering substances than the corresponding extracts obtained by the liquid-liquid technique.
已经研究了用Tenax从水中萃取有机微污染物（如农药和多氯联苯）的方法，并且观察到，即使存在其他污染物（油、表面活性物质等），使用Tenax - 硅藻土吸附柱获得的结果与连续液 - 液萃取技术获得的结果相当。对于含有悬浮固体且这些固体吸附农药的天然水，在用Tenax萃取之前可能需要对水进行过滤，然后分别萃取悬浮固体。对萃取前过滤的河水和河口海水的分析表明了Tenax的有效性，并且用于农药分析的提取物被干扰物质污染的程度远低于通过液 - 液技术获得的相应提取物。
