“…The data of recently published studies on the adsorption of emerging pollutants by PANI-based adsorbents are given in Table 4. These studies reported the removal of EPs, such as drugs [171], insecticides [172], bisphenol A (BPA) [173], personal care products [174], PFASs [175], PCBs [176], endocrine disrupting compounds (EDCs) [73] by PANI-based adsorbents mainly at relatively high pH values (e.g. 5-7).…”

“…The study concluded that immobilizing AgNPs on the water treatment polymer membrane has the capacity to minimize particular toxicity challenges. Vijayalakshmi et al [103] reported the fabrication of a polymeric nanocatalyst that holds the potential to decompose traces of the antibiotic drug ciprofloxacin (CIP) in pharmaceutical wastewater. Because polyaniline (PANI) is known to hold promise as a material of choice for such application processes due to its conducting properties and reactive NH-groups, they demonstrated that the photodecomposition of CIP was feasible in pharmaceutical wastewater under UV-light aided by the fabricated Zirconium oxide (ZrO 2 )/PANI nanocomposite material.…”

They posited that after approximately 2 h, nearly 96% of the CIP in the wastewater sample was decomposed [103].…”

In the past decades, the demand for potable and usable water has been on a continual increase, while its availability has been on an exponential decline. Studies have argued that, by 2050, only a small fraction of the world's population will have access to clean and safe water, thereby exposing a significant portion of the population to a serious water crisis. Large volumes of wastewater are generated yearly, both domestically and industrially, and the necessity to develop effective and efficient strategies and technologies to recover these wastewaters and turn them into safe and reusable waters is a momentous concern among scientists and policymakers. Across the globe, governments are developing approaches and strategies to mitigate both short-and long-term water challenges resulting from various anthropogenic activities that have contributed to the rising degradation of water quality, coupled with the attendant negative impact of natural disasters, increasing urbanization, among others. Notwithstanding, the advancements in nanotechnology have made it possible to engineer novel and innovative polymer-based materials and composites that possess desirable and even predictable properties for targeted applications, which has presented the opportunity for the development of cost-effective nanotechnologies and processes employed in water remediation, reclamation, purification, and treatment processes worldwide. Nevertheless, these innovative technologies and processes have also been shown to have their limitations and challenges in the enhancement of water quality. Herein we survey the current advancement of selected polymer-based membranes and composites and their intervention for the production of safe, potable, and usable water, as well as their limitations, challenges, recommendations, and future perspectives.

Phenol compounds are used in many industrial areas. Due to their high toxicity and stability, phenol compounds are carcinogenic to humans and animals even at low concentrations during their production and use. For this reason, the removal of phenol contaminants is both necessary and beneficial. Water pollution caused by phenols is one of the most serious problems globally, threatening both people and the environment. Increasing industrial and human activities have led to an increase in wastewater discharge into water resources. These phenolic chemicals are harmful, and although there are different methods used, it is very important to find new materials and effective methods to remove these pollutants from water. This study aimed to convert the phenols purified from water using tyrosinase paste to a less harmful state by making an enzymatic biofilter for phenol removal, thanks to the polyaniline structure we formed on the filter paper, to ensure phenol retention. While this process took place, FeCl3 solution was used as the reactor material, and aniline was turned into polyaniline with FeCl3 solution in HCl. While these processes are being carried out, it is aimed to prepare the most efficient biofilter by using the components that make up the experiment at different concentrations. By calculating the % efficiency of the catechols, absorbance values were measured before and after filtration. It was revealed that the highest percentage of biofilter activity was formed using 0.15 M aniline, 10 KU tyrosinase enzyme, and 1% chitosan concentrations.
