Geochemical modeling has been employed in several fields of science and engineering in recent years. This review seeks to provide an overview of case studies that applied geochemical modeling in the 2019 year, which includes over 250 articles. This review is intended to inform new users on the possibilities that geochemical modeling brings, while also informing existing and past users on its latest developments. The survey of studies was conducted with an emphasis on the modeling techniques, the objective of studies, the prevalent simulated variables and the use of specific software packages. The analysis showed that geochemical modeling is still predominantly employed in experimental projects and in the form of equilibrium modeling. PHREEQC and Visual MINTEQ were recognized as the most popular software packages for simulating a wide range of processes, using equilibrium or other geochemical modeling forms. The study of fluid–rock interactions and pollution and remediation processes can be regarded as the principal geochemical modeling objectives, constituting 37% and 36% of the reviewed studies, respectively. Focusing on fluid–rock interactions, hydrogeochemical processes, carbon capture and storage and enhanced oil recovery have been the main topics examined with geochemical modeling. Assessments of the toxicity of metals in terms of leachate and mobilization, as well as their removal from soil and water systems, have been major topics investigated with the aid of geochemical modeling in terms of pollution and remediation research. It was found that the scholars benefit from geochemical modeling in their research both as a main technique and as an accessory tool. Saturation index, elemental concentration and speciation, mineral mass and composition and pH were among the most common variables modeled in reviewed studies. Geochemical modeling has gained a wider user base in recent years, and many research groups have used it in consecutive studies to deepen knowledge. However, much potential for further dissemination still remains.

近年来，地球化学建模已应用于多个科学和工程领域。本综述旨在概述 2019 年应用地球化学建模的案例研究，其中包括 250 多篇文章。这篇评论旨在让新用户了解地球化学建模带来的可能性，同时也让现有和过去的用户了解其最新发展。研究调查的重点是建模技术、研究目标、流行的模拟变量和特定软件包的使用。分析表明地球化学模拟仍然主要用于实验项目和平衡模拟的形式。PHREEQC 和 Visual MINTEQ 被认为是最流行的软件包，用于模拟各种过程，使用平衡或其他地球化学建模形式。流体-岩石相互作用以及污染和修复过程的研究可被视为主要的地球化学建模目标，分别占所审查研究的 37% 和 36%。关注流体-岩石相互作用、水文地球化学过程、碳捕获和储存以及提高石油采收率一直是地球化学建模研究的主要主题。在污染和修复研究方面，借助地球化学模型，对金属在渗滤液和迁移方面的毒性以及从土壤和水系统中的去除进行评估，已成为主要研究课题。发现学者们在他们的研究中受益于地球化学建模，既是主要技术，也是辅助工具。饱和指数、元素浓度和形态、矿物质量和成分以及 pH 值是审查研究中最常见的建模变量。近年来地球化学建模获得了更广泛的用户群，许多研究小组在连续研究中使用它来加深知识。然而，进一步传播的潜力仍然很大。并且许多研究小组在连续的研究中使用它来加深知识。然而，进一步传播的潜力仍然很大。并且许多研究小组在连续的研究中使用它来加深知识。然而，进一步传播的潜力仍然很大。
