Results of Ion Chromatography

We synthesized two calcium carbonates, calcite and aragonite, to understand the properties of Na ion during its partitioning into calcium carbonates.

Worksheet "ion chromatography" represents the calculation of partitioning coefficients (Kd) of Na between solvent and CaCO3.
Lines B and C: the water temperature during the precipitation of CaCO3 and the unit, respectively.
Lines D and E: the Ca++ concentrations in the solvent and the unit, respectively.
Line F: repetition number.
Line G: Date of analysis.
Line H: Apparent partitioning coefficients (Kd) calculated from Na/Ca ratios in the solvents (m) and synthesized calcium carbonates (x) as
Kd = (Na/Ca)x/(Na/Ca)m.
Line I, J and K: Na+, Mg++, Ca++ concentrations in CaCO3 after the dissolution and dilution.

Worksheet "other info." represents the other parameters used in this study.

本研究中，我们合成两种碳酸钙——方解石和霰石，以探究钠离子在其分配至碳酸钙过程中的性质。工作表“离子色谱”记录了溶剂与碳酸钙之间钠离子分配系数（Kd）的计算过程。其中，B列和C列分别记录了碳酸钙沉淀过程中水温及其单位。D列和E列分别记录了溶剂中的钙离子浓度及其单位。F列表示重复次数。G列记录了分析日期。H列展示了通过溶剂（m）和合成碳酸钙（x）中钠钙比计算得出的表观分配系数（Kd），其计算公式为Kd = (Na/Ca)x / (Na/Ca)m。I列、J列和K列分别记录了溶解和稀释后碳酸钙中的钠离子（Na+）、镁离子（Mg++）和钙离子（Ca++）浓度。此外，工作表“其他信息”则包含了本研究中使用的其他参数。
