Dissolved and total dissolvable manganese concentrations at station TT045_13-2

Current values have been verified by comparison to the NASS-4 SRM and by DDDC/APDC extraction with GFAAS analysis.本次测定值已通过与NASS-4 标准参考物质（Standard Reference Material, SRM）比对，以及采用二乙基二硫代氨基甲酸钠/吡咯烷二硫代甲酸铵（Diethyldithiocarbamate/ Ammonium Pyrrolidinedithiocarbamate, DDDC/APDC）萃取结合石墨炉原子吸收光谱法（Graphite Furnace Atomic Absorption Spectroscopy, GFAAS）分析的方式完成验证。
