| 摘要 |
The proposed equipment comprises a control and signal processing unit, measuring vessels, electrolytic pre-concn. vessel, power supply unit, pumps and auxiliary electrolyte storage vessel. The sample inlet is connected to the auxiliary electrolyte vessel (2) via the pump (3). The stream to be analysed is passed through a divider (4) and pumps (3). One part of the stream (5) is passed through the anode space of the pre-concn. vessel(s). The other stream is passed through the cathode space of the same vessel. The discharge (10) of the cathode space is connected to drain. The discharge (11) of the anode space is connected to the inlet (12) of the measuring vessel (13), and also via a de-gasser (14) to drain (15). The control and signal processign unit (16) is connected to the first electrode (17) of the measuring vessel (13), also the second electrode (18) and to the reference electrode (24). The power supply unit (15) is electrically connected to the first (17) and second electrode (18) of the measuring vessel (13) and to the cathode (20) and anode (21) of the pre-concn. vessel (9 |
