Contamination in the environment is a major concern because of the harmful effects on ecosystems and human health, and dyes are increasingly common industry-contributed pollutants. This book offers a comprehensive analysis of the primary, secondary, and tertiary wastewater treatment systems that are in use across the globe. Covering the latest research in water purification techniques, the book contains analysis of photocatalysis and the mechanisms involved, findings of an in-depth investigation into different dyes, their preparation and the threats they pose, and concludes with discussion of the chemistry of green biopolymers and their doping impact with metal, metal oxides, and metal sulphide nanomaterials. The book will appeal to researchers and postgraduate students working in the fields of materials science, nanoscience and nanotechnology for environmental remediation.
