The presence of pollutants such as organic dyes and heavy metals in water has become a serious problem for aquatic environment. These pollutants that reach the human body through drinking water pose a serious threat to human life. These pollutants can be responsible for diabetes, cancer, high blood pressure, cardiovascular, neurological arteriosclerosis, and many other serious diseases in the human body. The elimination of such water pollutants is an urgent need of the society. But the present adsorption techniques available are costly and out of reach of the masses. The biofilm formation by bacterial cells onto the solid surface is also a subject of concern. In this regard, many efforts have been made to achieve an effective adsorption technology. Adsorption technology using Nigella Sativa and its composites has gained attention because of the biofilm resistance activities of the Nigella Sativa. Owning to its unique physicochemical characteristics, antibacterial properties of Nigella Sativa based composites provide a preferred material for water treatment. This review puts in a nutshell the application of Nigella Sativa based composites for water treatment. The methods of synthesis and physio-chemical properties Nigella Sativa based materials by making use of various techniques have been discussed in depth. Pollutants removals from water have been discussed in light of various parameters that affect it. The implementing and reusing of the adsorbent are also detailed out. The comparative cost, antibacterial activity, adsorption capacities and partition coefficients have also been discussed. This review will definitely be useful for the scientific community to develop the more sustainable material for water purification with high quality.

水中有机污染物和重金属等污染物的存在已成为水生环境的严重问题。这些通过饮用水进入人体的污染物对人类生命构成了严重威胁。这些污染物可能导致糖尿病，癌症，高血压，心血管疾病，神经性动脉硬化以及人体中许多其他严重疾病。消除这种水污染物是社会的迫切需要。但是，目前可用的吸附技术是昂贵的并且是大众无法达到的。细菌细胞在固体表面上形成生物膜也是一个令人关注的问题。在这方面，已经进行了许多努力来获得有效的吸附技术。使用Nigella Sativa及其复合材料的吸附技术由于Nigella Sativa的生物膜抗性而受到关注。由于其独特的理化特性，基于Nigella Sativa的复合材料的抗菌性能为水处理提供了一种首选材料。这篇综述概括了基于Nigella Sativa的复合材料在水处理中的应用。已经深入讨论了利用各种技术合成和合成基于Nigella Sativa的材料的方法。已经根据影响水的各种参数讨论了从水中去除污染物的方法。还详细介绍了吸附剂的实现和再利用。还讨论了比较成本，抗菌活性，吸附能力和分配系数。
