详情介绍:

   含砷较低时,导致生长滞缓,怀孕减少,自发流产较多,死亡率较高。骨骼矿化减低,在羊和微型猪还观察至心肌和骨骼肌纤维萎缩,线粒体膜有变化可破裂。砷在体内的生化功能还未确定,但研究提示砷可能在某些酶反应中起作用,以砷酸盐替代磷酸盐作为酶的激活剂,以亚砷酸盐的形式与巯基反应作为酶抑制剂,从而可明显影响某些酶的活性。有人观察到,在做血透析的患者其血砷含量减少,并可能与患者神经系统紊乱、血管病有关。
    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、工业污水处理厂污水、市政污水处理厂污水等场合。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。

    When arsenic is low, it leads to slow growth, reduced pregnancy, more spontaneous abortion, and higher mortality. Skeletal mineralization is reduced, and myocardial and skeletal muscle fibers are also atrophied in sheep and miniature pigs, and changes in the mitochondrial membrane can be broken. The biochemical function of arsenic in the body has not been determined, but studies suggest that arsenic may play a role in some enzyme reactions, using arsenate instead of phosphate as an activator of the enzyme, reacting with sulfhydryl groups as arsenite as an enzyme inhibitor. Agents, which can significantly affect the activity of certain enzymes. It has been observed that blood arsenic levels are reduced in patients undergoing hemodialysis and may be associated with neurological disorders and vascular disease in patients.
     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, industrial sewage treatment plant sewage, municipal sewage treatment plant sewage 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方法测定,水样和调节剂混合后,各类形式的砷转变为砷离子,砷离子在碱性环境和增敏剂存在的情况下,与指示剂反应生成一种带色络合物,分析仪检测此颜色的变化,并把这种变化换算成总砷值输出来。生成的带色络合物量相当于总砷量。

本方法适用于总砷在0-10mg/L范围内的废水。

Product principle:

This product is measured by spectrophotometric method. After mixing water and conditioner, various forms of arsenic are converted into arsenic ions. In the presence of alkaline environment and sensitizer, arsenic ions react with the indicator to form a belt. The color complex, the analyzer detects this color change and converts this change into a total arsenic value output. The amount of colored complex formed is equivalent to the total amount of arsenic.
     The method is applicable to wastewater with total arsenic in the range of 0-10 mg/L.
