Abstract
Lignin is an amorphous natural polymer with multifunctional phenolic network accounting for approximately 15–30% of lignocellulosic biomass. Different functional groups like carboxyl, hydroxyl, phenolic and methoxy in lignin molecule may act as suitable interaction sites for the removal of pollutants. Lignin, as an abundant and renewable bioresource, can be used to create nanofibrous membranes via electrospinning technique. Such nanofibrous membranes with elevated specific surface area, uniform fiber diameter, and high porosity may serve as highly efficient adsorbents for the entrapment of detrimental pollutants like dyes, heavy metals, particulates, etc. Hence, numerous research has been carried out to develop lignin based electrospun membranes in recent years. For example, a low-cost electrospun nano-fibrous membrane (ENM) comprising of alkali lignin/polyvinyl alcohol (PVA) was developed for effective removal of Safranine T dye. Similarly, palm fronds and banana bunch waste biomass derived lignin was successfully employed as an electrospun material for the removal of methylene blue dye. An alkali lignin/PVA ENM was developed for the adsorption of fluoxetine contaminant from its solution. This review paper provides the up-to-date information on the development and usage of eco-friendly, sustainable and cost-effective electrospun lignin nano-adsorbents for the removal of various environmental contaminants.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
