Inadequately treated or untreated wastewater greatly contribute to the release of unwanted toxic contaminants into water bodies. Some of these contaminants are persistent and bioaccumulative, becoming a great concern as they are released into the environment. Despite the abundance of wastewater treatment technologies, the adsorption method overall has proven to be an excellent way to treat wastewater from multiple industry sources. Because of its significant benefits, i.e., easy availability, handling, and higher efficiency with a low cost relative to other treatments, adsorption is opted as the best method to be used. However, biosorption using naturally found seaweeds has been proven to have promising results in removing pollutants, such as dyes from textile, paper, and the printing industry, nitrogen, and phosphorous and phenolic compounds, as well as heavy metals from various sources. Due to its ecofriendly nature together with the availability and inexpensiveness of raw materials, biosorption via seaweed has become an alternative to the existing technologies in removing these pollutants from wastewater effectively. In this article, the use of low-cost adsorbent (seaweed) for the removal of pollutants from wastewater has been reviewed. An extensive table summarises the applicability of seaweed in treating wastewater. Literature reported that the majority of research used simulated wastewater and minor attention has been given to biosorption using seaweed in the treatment of real wastewater.
未经处理或处理不当的废水会大量释放出不需要的有毒污染物到水体中。其中一些污染物具有持久性和生物累积性，一旦释放到环境中，就会成为一个严重的问题。尽管有大量的废水处理技术，但吸附法总体上已被证明是处理来自多个工业源废水的一种极好方法。由于其具有显著的优势，例如相对于其他处理方法更容易获得、处理和更高的效率，同时成本更低，因此吸附被选为最佳的处理方法。然而，利用天然存在的海藻进行生物吸附已被证明在去除污染物方面具有很大的潜力，如来自纺织、造纸和印刷行业的染料、氮、磷和酚类化合物以及各种来源的重金属。由于其环保特性以及原材料的易得性和廉价性，通过海藻进行生物吸附已成为从废水中有效去除这些污染物的现有技术的替代方法。本文综述了利用廉价吸附剂（海藻）从废水中去除污染物的方法。一个广泛的表格总结了海藻在处理废水方面的适用性。文献报道称，大多数研究都使用模拟废水，而对海藻在实际废水处理中的生物吸附作用的关注较少。
