六价铬测定试剂盒（专利号：ZL2004 2 0102870.1）
Chromium（Ⅵ） Test Kit
产品介绍：
环境中的六价铬来源主要是要电镀、治炼、表面处理工业等排放的污水、废气，六价铬对人体的毒性很大，可以通过消化道、呼吸道、皮肤及粘膜侵入人体，会引起多种疾病，并且六价铬有蓄积与致癌作用。
现在随着环保执法的加强，国内外都对环境与产品中残余六价铬的含量进行限定。在ROHS标准中，电子电气产品中六价铬的残余量有着严格的上限要求，随着相关法规的推行，国内电子五金、电镀、表面处理等行业的企业，对产品与排污水中的六价铬含量进检测已是企业必做的一项工作，但是传统的六价铬检测方法过于复杂，需要专业的技术人员与设备，检测成本高、周期长，无法在企业中得到广泛应用，不能满足快速的现场检测要求。
广东环凯微生物科技有限公司推的六价铬快速检测试剂盒与便携式比色仪产品满足了企业快速、准确的分析六价铬残余量的需求，有助于企业加强品质管理。产品基于国际的DPC方法，单次用量独立包装，结果与国际方法一致，产品获国家实用新型专利（ZL200420102870.1）
检测范围：0.05-0.1-0.2-0.3-0.4-0.6-0.8-1mg/L

用于检测固体国残余六价铬时可使用渚沸法转移其中的六价铬（方法参考GB/Z－21275－2007）
Chromium（Ⅵ） Test Kit
Easy to Operate:
Users do not require special training, and can refer to the use instruction on the colorimetric card, and independently finish water testing in 10 minutes per water sample.
Accurate Measuring:
Testing methods are conducted under international standards, with a range of 0-1.0 mg/L.
Convenient Packs:
Every pack is for 100 tests with attributes of small size, lightweight and convenience for carrying.
Fields of Application:
Household drinking water and water sources, bottled water; surface water, aquiculture water, irrigation water, seawater, household and industrial wastewater and etc
Various industries involving large amount of water require frequent water testing, and the controlling of water quality to meet the different standards. In the case of water deterioration, water tests must be conducted immediately, so measures can be taken accordingly, to prevent serious consequences caused.
Huankai has released water testing packs, and the test is quick, accurate and simple. The testing packs are very convenient for on site operation, and can satisfactorily meet the requirements in various industries.
On top of current water testing products, Huankai has recently released new Cr (Ⅵ) testing packs, further improving this type of water testing pack, and has brought more conveniences to our customers.
Development Background:
Sources of Cr Pollution:
Major Cr pollutions usually come with the waste water and smoke released from mining and mineral processing industries, smelting and plating industries, machine, automobile, and aircraft manufacturing, dyeing, printing, and pharmaceutical industries, etc.
Hazard Caused by Cr:
Cr is one of the minor elements in organisms. However, large amount of Cr present can contaminate the environment, and is also harmful to our health. All chemicals containing Cr are toxic. Cr6+ is most toxic, which is 100 times more toxic than Cr3+, and Cr2+ is least toxic. Most Cr chemicals can accumulate in biological bodies.
Usually, Cr (Ⅵ) is the cause of most Cr poisoning. Clinical symptoms can vary depending on the ways of contact. Drinking contaminated water can cause sick feeling and diarrhea, etc. Skin contact with Cr can cause irritation, dermatitis, or eczema, which has symptoms of having many small coin shape inflammations; they are subacute, red spotted, infiltrating, peeling, and slow healing. Inhalation of Cr can cause irritation, corrosion to airway and also inflammation in nasal cavity, throat, and bronchia. When serious, it can even cause erosion and ulcers in nasal cavity. Cr is also carcinogenic.
