Data for: Equilibrium fractionation of stable strontium isotopes during adsorption of Mn oxides

Concentration and stable isotopic composition of Sr in dissolved and adsorbed phases during adsorption experiments. Different conditions, such as adsorption time, initial Sr concentration, pH, and ionic strength, were set in the experiments. The equilibrium fractionation better describes liquid-solid Sr isotope fractionation during adsorption by Mn oxides, and the fractionation in synthetic seawater is consistent with the Sr isotopic offset between seawater and ferromanganese nodules, indicating that adsorption of Sr by Mn oxides is the dominant process of Sr enrichment in ferromanganese deposits.吸附实验中溶解相与吸附相的锶（Sr）浓度及稳定同位素组成。本次实验设置了吸附时长、初始锶浓度、pH值与离子强度等不同实验条件。平衡分馏模型可更恰当地描述氧化锰（Mn oxides）吸附过程中的液-固锶同位素分馏行为；人工合成海水中的分馏结果与海水和铁锰结核之间的锶同位素偏移量相符，表明氧化锰对锶的吸附作用是铁锰矿床中锶富集的主导过程。
