吸附栅栏环技术特别适用于测定某些对热不稳定的有机化合物。这种方法的特点是先用通常的环炉冲洗技术制备吸附栅栏环(以下简称吸附环)但在其后的成分检测时不用环炉,特别适用于现场监测,本文报告了一种不用环炉制作吸附环的新方法,结合使用疏水栅栏环技术测定了大气中的氟化氢,因本法自始至终不用环炉,故称其为不用环炉的环比色法。本法与锆-二甲酚橙比色法作了比较,得到了一致的结果。
Adsorption barrier ring technology is particularly suitable for the determination of certain thermally unstable organic compounds. This method is characterized by first using conventional ring furnace rinse technology to prepare adsorption fence ring (hereinafter referred to as adsorption ring), but in the subsequent composition of the test without ring furnace, especially for on-site monitoring, this paper reported a ring furnace The new method of making adsorption rings, combined with the use of hydrophobic barrier ring technology, determines the presence of hydrogen fluoride in the atmosphere, because it does not use a ring furnace throughout, so it is referred to as a ring colorimetric method without a ring furnace. This method is compared with the zirconium-xylenol orange colorimetric method, and the results are consistent.
