In recent years, pollutants released into the environment from various sources threaten environmental health. Rapid industrialization and the constantly increasing needs of people facilitate the release of more hazardous wastes into the ecosystem. The presence of pollutants in water resources causes a wide range of adverse effects. In this study, calcium phosphate nanomaterial (Ca(PO) NM) was synthesized from biological waste eggshells for the cadmium removal in synthetic domestic wastewater, and a treatment method was developed using these NMs. The Ca(PO) NMs were produced by using a biowaste which provides the synthesis procedure greener approach. The biogenic NMs were used to remove toxic cadmium ions from wastewater samples. Cytotoxicity and genotoxicity studies of the synthesized NMs were also carried out, and their possible effects on the health of living organisms and the ecology were examined. In the developed method, the parameters affecting the removal of cadmium from wastewater samples were optimized and the removal efficiency was calculated by determining cadmium in a flame atomic absorption spectrophotometer system (FAAS). Synthetic domestic wastewater samples were utilized for evaluating the applicability of the developed treatment strategy. In addition, the adsorption capacity of the material for Cd ion was calculated and the values obtained were modeled by using Langmuir adsorption isotherm (LAI). The calculated LAI parameters were within the appropriate limits, which proved that the developed NM can be used as an effective material for cadmium removal. Moreover, a new, rapid, and feasible synthesis strategy for the synthesis of Ca(PO) NM was presented in the literature.
近年来，各种来源排放到环境中的污染物对环境健康构成威胁。快速工业化和人们不断增长的需求促使更多危险废物排放到生态系统中。污染物在水资源中的存在会导致广泛的不良影响。在这项研究中，从生物废物蛋壳中合成了磷酸钙纳米材料（Ca(PO) NM），用于去除合成生活废水中的镉，并开发了一种使用这些 NM 的处理方法。Ca(PO) NM 是通过使用生物废物来生产的，这种生物废物为合成过程提供了更环保的方法。生物纳米材料被用于从废水样品中去除有毒的镉离子。还对合成 NM 的细胞毒性和遗传毒性进行了研究，并检查了它们对生物体健康和生态的可能影响。在所开发的方法中，优化了影响从废水样品中去除镉的参数，并通过在火焰原子吸收分光光度计系统（FAAS）中测定镉来计算去除效率。利用合成的生活废水样品评估了所开发处理策略的适用性。此外，还计算了材料对 Cd 离子的吸附容量，并使用 Langmuir 吸附等温线（LAI）对获得的值进行建模。计算出的 LAI 参数在适当的范围内，这证明所开发的 NM 可作为去除镉的有效材料。此外，本文还提出了一种新的、快速的、可行的 Ca(PO) NM 合成策略。
