减少人类活动对自然环境负面影响的一种方法是在工业过程中使用天然、容易获得且相对便宜的化合物来生产化合物。其中一种化合物是天然存在的碳酸钙 (CaCO3)。该化合物具有吸附特性，因此可以替代常用的吸附剂。这项工作的目的是确定使用碳酸钙去除水中磺胺嘧啶和四环素等药物物质的可能性。这项工作中使用的 CaCO3 是使用我们自己的方法合成的，该方法可以生产纳米尺寸的 CaCO3 颗粒。在进行的研究中，碳酸钙以纯化溶液中的悬浮液形式使用，并作为所开发膜的无机填充物。在进行的测试中测定了从其水溶液中除去的药物物质的质量。根据所得结果，可以得出结论，CaCO3 具有吸附四环素和磺胺嘧啶的能力。悬浮试验中，单位质量吸附剂去除物质的质量分别为1.52mg/g和6.85mg/g。反过来，在使用所开发的膜的集成工艺的情况下，每单位质量的吸附剂去除的物质的质量为109mg/g和97mg/g。

Application of Calcium Carbonate in the Pharmaceutical Removal Process

One way to reduce the negative impact of human activity on the natural environment is to use natural, easily available and relatively cheap to produce compounds in industrial processes. One such compound is naturally occurring calcium carbonate (CaCO3). This compound has adsorption properties so that it can be an alternative to commonly used adsorbents. The aim of this work is to determine the possibility of using CaCO3 to remove pharmaceutical substances such as sulfadiazine and tetracycline from water. The CaCO3 used in this work was synthesised using our own method, which allows the production of CaCO3 particles with nanometric size. In the conducted research, calcium carbonate was used in the form of a suspension in purified solutions and as an inorganic filling of the developed membranes. The mass of pharmaceutical substances removed from their aqueous solutions was determined in the tests carried out. Based on the results obtained, it can be concluded that CaCO3 has the ability to adsorb both tetracycline and sulfadiazine. In suspension tests, the mass of the removed substances per unit mass of adsorbent was 1.52 mg/g and 6.85 mg/g, respectively. In turn, in the case of the integrated process using the developed membranes, the mass of the removed substances per unit mass of adsorbent was 109 mg/g and 97 mg/g.
