A non-optimised treatment of wastewaters containing organic and biological substances is very often accompanied by an accidental emanation of hydrogen sulphide H2S and therefore leads (i) to an undesirable odour in the vicinity of water treatment plants, and (ii) to a potential hazard for the neighbouring population. Fast, sensitive and reliable monitoring devices hence of significant importance. Chalogenide and chalcohalide glass are new promising membrane material for detection of heavy metal ions and toxic anions and particularly well adapted for continuous in situ monitoring and industrial process control. In the present paper, we will discuss analytical characteristics of new chalcogenide glass chemical sensors for detection of S2- and dissolved H2S, which slow reliable process control to be carried out at natural pH of wastewaters.
对含有有机和生物物质的废水进行非优化处理时,常常会意外释放出硫化氢(H₂S),因此会导致:(i)在水处理厂附近产生难闻气味;(ii)对附近居民构成潜在危害。因此,快速、灵敏且可靠的监测设备至关重要。硫族化物和硫卤化物玻璃是用于检测重金属离子和有毒阴离子的新型有前景的膜材料,特别适用于连续原位监测和工业过程控制。在本文中,我们将讨论用于检测S²⁻和溶解态H₂S的新型硫族化物玻璃化学传感器的分析特性,这些特性有助于在废水的自然pH值下进行可靠的过程控制。
