This review embarks on a comprehensive journey, exploring the application of lignocellulosic biomass materials as highly effective adsorbents for the removal of textile dyes (cationic and anionic dyes) from wastewater. A literature review and analysis were conducted to identify existing gaps in previous research on the use of lignocellulosic biomass for dye removal. This study investigates the factors and challenges associated with dye removal methods and signifies their uses. The study delves into the pivotal role of several parameters influencing adsorption, such as contact time, pH, concentration, and temperature. It then critically examines the adsorption isotherms, unveiling the equilibrium relationship between adsorbent and dye and shedding light on the mechanisms of their interaction. The adsorption process kinetics are thoroughly investigated, and a detailed examination of the adsorbed rate of dye molecules onto lignocellulosic biomass materials is carried out. This includes a lively discussion of the pseudo-first, pseudo-second, and intra-particle diffusion models. The thermodynamic aspects of the adsorption process are also addressed, elucidating the feasibility and spontaneity of the removal process under various temperature conditions. The paper then dives into desorption studies, providing insights into the regeneration potential of lignocellulosic biomass materials for sustainable reusability. The environmental impact and cost-effectiveness of employing lignocellulosic biomass materials in textiles including Congo Red, Reactive Black 5, Direct Yellow 12, Crystal Violet, Malachite Green, Acid Yellow 99, and others dyes from wastewater treatment are discussed, emphasizing the significance of eco-friendly solutions. In summary, this review brings together a wealth of diverse studies and findings to present a comprehensive overview of lignocellulosic biomass materials as adsorbents for textile cationic and anionic dye removal, encompassing various aspects from influential parameters to kinetics, adsorption isotherms, desorption, and thermodynamics studies. Its scope and other considerations are also discussed along with its benefits. The collective knowledge synthesized in this paper is intended to contribute to the advancement of sustainable and efficient water treatment technologies in the textile industry.

Herein a novel nanocomposite, Praseodymium oxide-nano montmorillonite (Pr-nMMT)was fabricated and explored as stabilising admixture for enhancing the strength of dredged soils. The compaction, permeability, direct shear, california bearing ratio (CBR), and unconfined compressive strength (UCS) tests performed on the dredged soil samples collected from the Shalimar site along the Dal Lake Srinagar rendered it unsuitable as construction material and needed stabilisation before using it as a building material. Different percentages of Pr-nMMT (0.25–1%) were used for stabilisation purposes and it revealed that the addition of Pr-nMMT to soil increased maximum dry density (MDD), shear strength parameters (angle of internal friction and cohesion), CBR, and decreased optimum moisture content (OMC), plasticity index, and hydraulic conductivity. The UCS enhanced notably with Pr-nMMT content and increment in curing time. The optimum Pr-nMMT content determined was 0.5% as it demonstrated the maximum value of UCS at 0, 7 and 14 days of curing beyond which the strength showed a declining trend. It was anticipated that Pr-nMMT filled pores between soil particles, therefore resisting sliding among soil particles and thus increasing the strength of treated dredged soil. The results portray Pr-nMMT as an efficient nano admixture for the stabilisation of dredged soil. [ABSTRACT FROM AUTHOR]
