详情介绍:

    铅是一种严重危害人类健康的重金属元素,它可影响神经、造血、消化、泌尿、生殖和发育、心血管、骨骼等各类器官,主要是神经系统和造血系统。更为严重的是它影响婴幼儿的生长和智力发育,损伤认知功能、神经行为和学习记忆等脑功能,严重者造成痴呆。特别是对于儿童,只要血铅水平超过或等于100微克/升,不管有没有临床症状、体征,都可以确诊为儿童铅中毒。国内外的大量研究表明,婴幼儿和儿童的血铅水平与智商显著相关等。
    铅引起的智力损害是不可逆转的。即经过驱铅后,血铅下降,但智力损害无明显恢复。铅中毒危害以神经系统受损极为严重,可导致小儿烦躁不安,易冲动,食欲下降,注意力不集中,性格改变,反应迟钝,智力下降,记忆力下降等。严重者可出现铅中毒脑病,甚至死亡。                                                                                                        

     Lead is a heavy metal element that seriously harms human health. It can affect nerves, hematopoiesis, digestion, urinary, reproductive and developmental, cardiovascular, bone and other organs, mainly the nervous system and hematopoietic system. More serious is that it affects the growth and mental development of infants and young children, damages brain function such as cognitive function, neurobehavior and learning and memory, and causes dementia in severe cases. Especially for children, as long as the blood lead level exceeds or equals 100 micrograms per liter, the lead poisoning can be diagnosed in children with or without clinical symptoms and signs. Numerous studies at home and abroad have shown that blood lead levels in infants and children are significantly associated with IQ.
     The intellectual damage caused by lead is irreversible. That is, after the lead was driven, the blood lead decreased, but the intellectual damage did not recover significantly. Lead poisoning damage is the most serious damage to the nervous system, which can lead to irritability, impulsiveness, loss of appetite, inattention, personality change, slow response, decreased intelligence, and decreased memory. In severe cases, lead poisoning encephalopathy can occur, and even death.

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,各类形式的铅转变为铅离子,铅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铅值输出来。生成的带色络合物量相当于总铅量。

本方法适用于总铅在0-10mg/L范围内的废水。

Product Principle:

This product is measured by spectrophotometric method. After mixing water sample and regulator, various forms of lead are converted into lead ions. Lead ions react with indicator to form a band in the presence of alkaline environment and sensitizer. The color complex, the analyzer detects this color change and converts this change into a total lead output. The amount of colored complex formed is equivalent to the total amount of lead.

     The method is applicable to wastewater with total lead in the range of 0-10 mg/L.
