Abstract
ABSTRACT Industrialization increases day by day and hence the demand of Cr (VI) compounds are also increased in tanning, electroplating, printing and in dyeing industries, which has resulted in considerable amounts of waste containing Cr(VI) being emitted. Environmental scientists are quite concerned about how much Cr(VI) is present in water since it creates a severe harm to the ecosystem and humans. Because of their functional diversity, high efficacy, economic viability, and simplicity of technical operation, low-cost biosorbents made of lignocellulosic biomasses have drawn attention for elimination of Cr(VI). One versatile and efficient approach to address Cr(VI) pollution is through the use of lignocellulosic materials, for biosorption. Within this comprehensive review, we conduct an impartial evaluation of the biosorption capabilities of various lignocellulosic biosorbents, while also examining the underlying mechanisms involved in the biosorption process by focusing on crucial variables including pH, contact time, dosage, and temperature. In addition, we assemble a list of investigated lignocellulose-based biosorbents that may be beneficial. In addition to offering our recommendations for future views, the review’s objective is to highlight existing trends, potential study areas, and obstacles to the practical use of the biosorption process.
