    Studies of ZnBi2O4 Nanoparticles for the Removal of Amido Black Dye
    (Book Rivers, 2026) Neda Afreen, Naseem Ahmad, Nafees Ahmad
    The study investigates the effectiveness of ZnBizO4 nanoparticles in removing Amido black, a prevalent and persistent pollutant in industrial wastewater. ZnBi2O4 nanoparticles were synthesized and characterized for their structural and optical properties, revealing a narrow band gap suitable for visible light photocatalysis. The photocatalytic performance of ZnBi₂O, was evaluated under various conditions, including catalyst dosage, initial dye concentration, pII, and irradiation time. Results demonstrated a high degradation efficiency of Amido black dyc, with nearly complete removal achieved under optimal conditions. Mechanistic studies indicated that the generation of reactive oxygen species (ROS) was crucial to the degradation process. The nanoparticles exhibited excellent stability and reusability, maintaining significant photocatalytic activity over multiple cycles. These findings underscore the potential of ZnBi2O4 nanoparticles as an effective and sustainable solution for wastewater treatment, capable of addressing the challenges posed by organic dye pollutants in industrial effluents. Future research directions include scaling up nanoparticle synthesis and exploring composite materials to further enhance photocatalytic performance.

    Microfluidic Devices: Harnessing the Power of Tiny Devices in Analysing Wastewater Quality
    (Springer nature, 2025) Zeba Sadia, Syed Sadiq Abbas, Saimah Khan, Jamal Akhtar Ansari
    The reduction in aquatic biodiversity and the growing water shortage are caused by habitat degradation and water pollution. Over the previous few decades, freshwater availability has decreased. Monitoring contaminants in wastewater effluents is essential to identifying areas of water contamination that require treatment. Multiple hazardous components in wastewater can be difficult to trace using conventional detection methods since they vary over time and come from different sources. There is increasing interest in making microfluidic apparatuses because of their phenomenal responsiveness, ease, dynamic response, negligible cost, constancy, and selectivity. Depicted by their ability to control small volumes of fluids through microchannels, they are emerging as moderate devices in normal checking, particularly in analysing wastewater quality. These miniature apparatuses furnish significant opportunities over the conventional approach, including reduced sample volume, faster processing times, high sensitivity, and the potential for on-site real-time analysis. Additionally, these systems can combine several analytical tasks into a single, small instrument, including sample preparation, segregation, identification, and quantification. Microfluidic devices can accurately measure contaminants like heavy metals, organic pollutants, pathogens, and nutrient levels. This chapter explores the applications of microfluidic technology in wastewater analysis, emphasizing its impact on improving water quality management and environmental protection.

    Antibiotic Pollution: Challenges and Strategies
    (Bentham Science, 2021) Saman Raza, Tahmeena Khan
    Antibiotics have been used as antimicrobial agents to fight a variety of infectious diseases, for the past more than 100 years. Apart from this, they are also extensively used in animal farming, agriculture, and aquaculture, all over the world. However, this frequent and large-scale overuse and incorrect use lead to the excessive dispersal of antibiotics in water and soil, resulting in their accumulation in the environment, which is known as antibiotic pollution. The removal of antibiotics from water and soil is complicated due to their non-biodegradable nature, and special techniques must be used for the same. This pollution has serious implications on both human health and the ecological balance. The major adverse effect is antibiotic resistance, wherein, microbes become less susceptible to treatment with antibiotics, posing problems for both the patient and the physician. This chapter describes the causes and consequences of antibiotic pollution, the challenges it presents, and the strategies to counter them.
