利用绿色植物减少采出水处理量

介绍一种应用植物对地层采出水进行处理的新方法，主体思想是从耐盐植物中挑选出高耐盐度和吸收蒸发速度快的植物。利用植物的这种天然能力，将需要处理的采出水体积减少。实验结果显示出这种方法可以减少其原来体积的75％。随后又将这种方法应用于具体的生产井，取得了良好的效果。采出水的体积减少了，耐盐植物生长得更加茂盛，植物的叶子被用来喂牛。这充分显示出此方法在环保方面的优势，对比发现这种方法在处理费用上也是非常节省的。

梯恩梯的植物处理

梯恩梯炸药污染环境，用传统的煅烧法处理不仅费用高昂，而且不尽彻底。该文介绍了美国乔治亚工学院等单位正在研究发展这中的植物处理法。如能用该方法处理梯恩梯的污染问题，既可大大节省开支，又对环境有利。

Photochemical Method to Evaluate Oxidation Levels in Heat-Treated Vegetable Oil： Comparison with Peroxide-Value and Acid-Value

To determine the degree of oxidation in vegetable oil, a photochemical method using the electron spin resonance （ESR） spin trapping technique was developed, and the results were compared with those obtained using conventional peroxide-value （PV） and acid-value （AV） methods. Vegetable oil heat-treated were subjected to short UV illumination, and the produced alkyl-oxyl radicals were identified and quantified using the ESR spin trapping technique. ESR signal intensity was used as an indicator of oil oxidation, which monotonically increased as a function of the heat-treatment time. Commercially, available oils were selected and analyzed. The results were compared with those obtained using the PV and AV methods. The present method displayed some analogies with the PV method at least in the early stage of heating. Overall, the present method had highly sensitive and capable of detecting early-stage oxidation in vegetable oil.
