Ni releases (镍释放)检测
1. Nickel release (Ni)镍释放是什么?

Nickel(Ni)镍近似银白色、硬而有延展性并具有铁磁性的金属元素,它能够高度磨光和抗腐蚀。镍属于亲铁元素。在地核中含镍最高,是天然的镍铁合金。在地壳中铁镁质岩石含镍高于硅铝质岩石



2. Nickel release (Ni)镍的应用及危害:

因为镍的抗腐蚀性佳,常被用在电镀上。主要用于合金(配方)(如镍钢和镍银)及用作催化剂(如拉内镍,尤指用作氢化的催化剂),可用来制造货币等,镀在其他金属上可以防止生锈。

Nickel(Ni)镍是一种容易导致接触性过敏的元素。镍元素通过一些含镍材料的释放并长期与皮肤接触后会被皮肤吸收,从而对部分个体导致过敏;进一步暴露在可溶性镍盐中会导致国民性接触性皮炎(据统计,20%的人对镍有很明显的过敏反应症状)。
