ASTM D5462-2013 在线测量水中低水平溶解氧的标准试验方法
简介：5.1x00a0;DO may be either a corrosive or passivating agent in boiler/steam cycles and is therefore controlled to specific concentrations that are low relative to environmental and wastewater treatment samples. Out-of-specification DO concentrations may cause corrosion in boiler systems, which leads to corrosion fatigue and corrosion productsx2014;all detrimental to the life and efficient operation of a steam generator. The efficiency of DO removal from boiler feedwater by mechanical or chemical means, or both, may be monitored by continuously measuring the DO concentration before and after the removal process with on-line instrumentation. DO measurement is also a check for air leakage into the boiler water cycle. 5.2x00a0;Guidelines for feedwater to high-pressure boilers with all volatile treatment generally require a feedwater DO concentration below 5 x03bc;g/L (3). 5.3x00a0;Boiler feedwater with oxygenated treatment is maintained in a range of 50 to 300 x03bc;g/L DO (4). 5.4x00a0;In microelectronics production, DO can be detrimental in some manufacturing processes, for example, causing undesirable oxidation on silicon wafers. 1.1x00a0;This test method covers the on-line determination of dissolved oxygen (DO) in water samples primarily in ranges from 0 to 500 x03bc;g/L (ppb), although higher ranges may be used for calibration. On-line instrumentation is used for continuous measurements of DO in samples that are brought through sample lines and conditioned from high-temperature and high-pressure sources when necessary. 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards statements, see 6.5.

GB/T 7489-1987 水质溶解氧的测定碘量法
简介：碘量法是测定水中溶解氧的基准方法。在没有干扰的情况下，此方法适用于各种溶解氧浓度大于0.2mg/L和小于氧的饱和浓度两倍（约20mg/L）的水样。易氧化的有机物，如丹宁酸、腐植酸和木质素等会对测定产生干扰。可氧化的硫的化合物，如硫化物硫脲，也如同易于消耗氧的呼吸系统那样产生干扰。当含有这类物质时，宜采用电化学探头法。亚硝酸盐浓度不高于15mg/L时就不会产生干扰，因为它们会被加入的叠氮化钠破坏掉。如存在氧化物质或还原物质，需改进测定方法，见第8章。如存在能固定或消耗碘的悬浮物，本方法需按附录A中叙述的方法改进后方可使用。
