摘　　要：研究了在近中性介质中,硝酸根与亚硝酸根的紫外吸收光谱,提出了引用"K比例H点标准加入法"同时测定了硝酸根、亚硝酸根含量的方法.并测定了合成水样及环境水样中硝酸根和亚硝酸根含量,结果满意.A method called ＂ K-Ratio H-Point Standard Addition Method＂ was proposed for the simultaneous determination of nitrate and nitrite,based on their ultraviolet absorption spectrum in a neutral medium. This method is applied to determination of nitrate and nitrite in synthetic water samples and surrounding water samples satisfactory results are obtained.

关 键 词：K比例H点标准加入法 硝酸根 亚硝酸根
