产品介绍
Phthalic Acid Esters (Phthalic Acid Esters, PAEs) mainly used for plastic plasticizer, its enter human body and animal will be similar to the role of estrogen in the body, endocrine disruptors, lead to the proliferation of cancer cells and can cause acute poisoning. And phthalate (2 -) ethyl hexyl ester (DEHP) is the only listed as "drinking water health standard" carries on the control and monitoring of phthalic acid esters. DEHP is similar to the effect of artificial hormones, can damage the male reproductive ability and promote female precocious puberty, a large number of long-term intake can lead to liver cancer. Because the child is in pubertal reproductive system, endocrine system DEHP to children's potential harm will be bigger. DEHP poorly soluble in water, in water are trace exist, therefore in the detection, enrichment of the DEHP in the water first. The gb standard test methods for domestic and drinking water in the DEHP in the water to make use of cyclohexane liquid-liquid extraction (LLE), but this method in the enrichment of component content is low, need to collect a large number of samples, not only the intensity of labor is big, and organic solvent dosage, pretreatment work multifarious, easy to cause pollution to the environment and harm to personnel.
xiang ying analysis technology co., LTD adopts XingyingngGC7990plus gas chromatograph to determine the water quality of phthalic acid esters, satisfied results.
邻苯二甲酸酯(Phthalic Acid Esters ,PAEs) 主要用作塑料增塑剂，其进入人体和动物体内会有类似雌激素的作用，干扰内分泌，导致癌细胞增殖，并可引发急性中毒。而邻苯二甲酸二（2-乙基己基）酯（DEHP）更是唯一被列入《生活饮用水卫生标准》进行控制与监测的邻苯二甲酸酯类。DEHP的作用类似于人工荷尔蒙，会损害男性生殖能力并促使女性性早熟，长期大量摄取会导致肝癌。由于幼儿正处于内分泌系统生殖系统发育期，DEHP对幼儿带来的潜在危害会更大。DEHP难溶于水，在水中都是以痕量存在，因而在检测中，需要先对水中的DEHP加以富集。国标《生活饮用水标准检验方法》中利用环己烷对水中的DEHP进行液液萃取 (LLE)，但该方法在富集组分含量较低时，需要采集大量样品，不仅劳动强度大，而且有机溶剂用量大，前处理工作繁杂，容易造成对环境的污染和对人员的伤害。
滕州市翔鹰分析技术有限公司采用XingyingngGC7990plus气相色谱仪测定水质邻苯二甲酸酯含量，结果满意。
