摘要	本发明涉及一种水质六价铬全自动快速测量系统及其测量方法，第一电磁阀与六价铬标准溶液、第二电磁阀连接，又通过蠕动泵连接到六通阀的第一接口，第二电磁阀与标样连接，六通阀的第二接口与第五接口通过定量环连接，六通阀的第六接口连接废液，六通阀的第三接口通过蠕动泵连接到载流液，六通阀的第四接口通过三通混合器分别与反应管一端和通过蠕动泵的显色剂连接，第三电磁阀分别连接到反应管另一端和空气，第三电磁阀又通过光电检测装置连接到废液。本系统具有流路设计简单、纯数字化光电检测、排除气泡干扰等优点，同时使用PLC可编程控制器，大大降低了仪器控制系统故障率,使仪器真正实现了无人值守全自动化测定。
其他摘要	The invention relates to a full-automatic quick measurement system and method for water quality hexavalent chromium. A first electromagnetic valve is connected with a hexavalent chromium standard solution and a second electromagnetic valve and then is connected to a first joint of a six-way valve through a peristaltic pump; the second electromagnetic valve is connected with a standard sample; a second joint of the six-way valve is connected with a fifth joint through a quantifying ring; a sixth joint of the six-way valve is connected with waste liquid; a third joint of the six-way valve is connected to current carrying liquid through the peristaltic pump; a fourth joint of the six-way valve is connected with one end of a reaction pipe and a development agent passing through the peristaltic pump respectively through a three-way mixing machine; a third electromagnetic valve is connected to the other end of the reaction pipe and air respectively; and the third electromagnetic valve is also connected to the waste liquid through a photoelectric detection device. The full-automatic quick measurement system has the advantages of simple flow path design, pure digital photoelectric detection, bubble interference elimination and the like; and furthermore, a programmable logic controller (PLC) is used, so that the fault rate of an instrument control system is greatly reduced, and an instrument can really carry out unmanned full-automatic measurement.
