Carbonate chemistry changes following iron and steel slags dissolution in seawater for Ocean Alkalinity Enhancement, and measured dissolution of potentially toxic elements.

Ocean alkalinity enhancement is a carbon capture strategy that has gained interest over the past years. This strategy relies on the dissolution of alkaline minerals to increase the alkalinity of the ocean, among which iron and steel slags are potential candidates. However, their dissolution in seawater as well as the leaching of potentially toxic elements is unknown. These data were collected as part of a research article that assess the alkalinity generation potential of iron and steel slags in MilliQ and seawater, as well as the dissolution of potentially toxic elements. The dataset is composed of various sheets, each of them reporting data from a specific experiment. For each experiment, the analysis details (instrument used, parameters analysed etc) are provided on each individual sheet, and an overview one regroups the main aims of this research as well as the technical terms used throughout.海洋碱化增强（Ocean Alkalinity Enhancement）是近年来广受学界关注的碳捕获策略。该策略通过溶解碱性矿物以提升海洋碱度，其中钢铁渣（iron and steel slags）是潜在的应用候选材料。然而，这类材料在海水中的溶解行为以及其中潜在有毒元素的溶出特性尚未明确。 本数据集源自一篇评估钢铁渣在超纯水（MilliQ）和海水中的碱度生成潜力，以及潜在有毒元素溶出特性的研究论文。数据集包含多个工作表，每个工作表对应一项特定实验的结果数据。针对每项实验，各工作表均附带了详细的分析信息（所用仪器、分析参数等）；另有一张总览工作表汇总了本研究的核心目标以及全文所用的专业术语。
