影响细菌反硝化法测量硝酸盐氧同位素的因素分析创新点:首次深入探究纯培养时的溶解氧浓度和硝酸盐进样量对同位素测试结果的影响及原因,可为氧同位素测试精度的提高提供方法和参考. 方法:通过控制培养瓶内的气液比(1:5、3:10、2:5和3:5)和摇床转速(60和120 r/min)来调节纯培养时的溶解氧浓度,并设计不同的硝酸盐进样量(0.05~1.00 µmol),由硝酸盐标准物质的测试结果判断适宜的溶解氧浓度和硝酸盐进样量. 结论:标准物质间的δ18O差值收缩主要受溶解氧浓度的影响.根据氧同位素测试结果的精度和δ18O差值收缩率的大小,得出以下结论:当普通三角瓶内的气液比为3:10,摇床转速为120 r/min时的溶解氧浓度最佳(1.9~2.6 mg/L),0.2~0.4 nmol的硝酸盐进样量最适宜. 关键词组: Darkslateblue:Affiliate; Royal Blue:Author; Turquoise:Article
