铁虽然是人体必需的微量元素。铁本身也不具有毒性,但当摄入过量或误服过量的铁制品时也可能导致铁中毒。急性铁中毒多发生在儿童,慢性铁中毒多发生在45岁以上的中老年人中,男性居多。据报道,铁中毒还可诱发癫痫病。 该分析仪能够根据现场设定长期无人值守自动连续工作,广泛适用于工业污染源排放废水、工业过程工艺废水等场合。根据现场测试工况的复杂程度,可选配相应的预处理系统,以保证测试过程可靠、测试结果准确,充分满足不同场合现场需求。
Although iron is an essential trace element in the human body. Iron itself is not toxic, but it can also cause iron poisoning when excessive intake or excessive use of iron products. Acute iron poisoning occurs mostly in children, and chronic iron poisoning occurs mostly in middle-aged and elderly people over 45 years old. Iron poisoning has also been reported to induce epilepsy. The analyzer can automatically and continuously work according to the on-site setting for long-term unattended operation, and is widely used in industrial waste water discharge, industrial process wastewater and other occasions. According to the complexity of the field test conditions, the corresponding pre-treatment system can be selected to ensure the test process is reliable and the test results are accurate, which fully meets the on-site requirements of different occasions.
产品原理:
本产品采用分光比色法测定,试样在一定酸度条件下,试样中的亚铁离子与指示剂生成红色配合物,分析仪检测此颜色的变化,并把这种变化换算成铁值输出来。生成的带色配合物量相当于铁量。
本方法适用于铁0-50mg/L范围内的废水。
Product principle:
This product is measured by spectrophotometric method. Under certain acidity conditions, the ferrous ion in the sample forms a red complex with the indicator. The analyzer detects the change of the color and converts the change into iron output. Come. The amount of colored complex formed is equivalent to the amount of iron.
The method is applicable to waste water in the range of 0-50 mg/L of iron.
