Description
技术领域
本发明属于冶金领域,更具体地,涉及一种测定偏钒酸钾废水中钒含量的方法。
背景技术
钒具有生物活性,是人体所必需的微量元素之一。钒可减少龋齿发病率,对造血过程有一定积极作用,并减弱合成胆固醇的作用,使血管收缩,增强心室肌的收缩力,还有降低血压的作用。天然水中钒含量很低,浓度大约为(1~10)μg/L,对人和动植物一般不会产生毒害作用。钒常作合金钢的添加剂和化学工业中的催化剂使用,因此钢铁、石油、化工、染料、纺织、陶瓷、照相、电子等工业废水中钒含量较多,因而造成污染。钒能抑制合成胆固醇的某些酶的作用,增加肝内磷脂的氧化。吸入体内会影响消化及神经系统,损害心脏及肾脏。当钒的浓度为0.8mg/L时,水有异味;浓度为10mg/L时,可抑制氨化作用和硝化作用,并使污水的自净能力降低;当浓度为(10~20)mg/L时可抑制大豆等作物的生长。
钒的测定方法主要有石墨炉原子吸收法,可测定(0.05~1.0)mg/L的钒;钽试剂(BPHA)萃取分光光度法可用于废水和0.05mg/L以上地表水中钒的测定;催化极谱法灵敏度最高,可测定地表水中(0.0002~0.016)mg/L的钒。近年来等离子体无机质谱法也开始用于饮用水中钒的测定,其检出限可达0.07μg/L。
然而,现有技术的测定方法确存在着分析速度慢,检测周期长的缺点。

为了解决上述问题,本发明提供了一种分析速度快,检测时间短的测定废水中钒含量的方法。
为了实现上述目的,本发明提供一种测定偏钒酸钾废水中钒含量的方法,所述测定钒含量的方法包括以下步骤:
以浓盐酸对偏钒酸钾进行消解;
将消解后的含钒溶液定容;
以电感耦合等离子体原子发射光谱仪测定含钒溶液中的钒含量。
本发明中,所述浓盐酸的质量百分比浓度为37%。
本发明中,每1mL浓盐酸中偏钒酸钾的用量为0.02-0.1g。
本发明中,可对定容后的溶液进行稀释。
本发明中,含钒溶液中的钒含量为8-50wt%。
与现有技术相比,本发明具有以下优点:
1、本发明所提供的方法分析速度快,检测时间短,测定的范围满足相关环保标准和环保工作的要求或国标要求;
