Dissolved concentrations of major elements and water isotopes for water sampl...

Water samples were filtered to 0.2 micron prior to measurement. Samples for cation analysis were acidified in the field to pH < 2 using 6N HNO3. Cation concentrations were...待测水样均经0.2微米滤膜过滤后进行检测。用于阳离子分析的样品，在采样现场使用6当量浓度的硝酸（HNO₃）酸化至pH值小于2。阳离子浓度分别为……
