原子吸收光谱法中产生化学干扰的原因及抑制办法


原子吸收光谱法是一种常用的分析方法,用于测定样品中的元素含量。然而,该方法在实际应用中可能会面临化学干扰。化学干扰是指在测定中,与目标元素发生化学反应或与其形成络合物,从而导致测定结果的失准。 产生化学干扰的原因包括以下几个方面: 1. 共存元素的影响:样品中可能存在其他元素,它们可能与目标元素发生化学反应,形成化合物或络合物,导致目标元素吸收信号减弱或消失。 2. 氧化还原反应:样品中可能存在氧化剂或还原剂,它们与目标元素发生氧化还原反应,改变目标元素的化学状态,导致吸收信号的变化。 3. 背景吸收:样品基质本身可能具有吸收光谱,称为背景吸收。背景吸收会遮挡目标元素的吸收信号,降低测定的准确性。 针对化学干扰,可以采取以下抑制办法: 1. 选择特定的波长:通过选择合适的测量波长,可以排除掉共存元素或样品基质的背景吸收干扰。这需要对样品和干扰物的光谱特性进行研究,以确定最佳的测量波长。 2. 校正方法:利用添加标准品、内标法或标准曲线法等校正技术,可以减少干扰造成的误差。这些方法可以提供准确的校正系数,将化学干扰纳入考虑,从而修正分析结果。 3. 概率散射技术:概率散射技术可以用于减少背景吸收干扰。这种技术是利用特定的几何装置和散射光强的测量,将背景吸收干扰减少到最小。 4. 选择合适的化学反应条件:通过调整样品的 pH 值、温度、氧化还原剂或络合剂的浓度等,可以控制化学反应的发生,减少干扰。 综上所述,针对原子吸收光谱法中的化学干扰问题,可以通过选择合适的测量波长、校正方法、概率散射技术和调整化学反应条件等方法来进行抑制。
