Dissolved and total dissolvable manganese concentrations at station TT045_19-16

Current values have been verified by comparison to the NASS-4 SRM and by DDDC/APDC extraction with GFAAS analysis.当前测定值已通过两种验证方式完成核验：其一为与NASS-4标准参考物质（Standard Reference Material, SRM）开展比对，其二为先采用二乙基二硫代氨基甲酸钠（Diethyldithiocarbamate, DDDC）与吡咯烷二硫代氨基甲酸铵（Ammonium Pyrrolidinedithiocarbamate, APDC）进行萃取，再通过石墨炉原子吸收光谱法（Graphite Furnace Atomic Absorption Spectroscopy, GFAAS）完成分析。
