“…[11][12][13] Despite these developments, the complete removal of organic dyes from the environment is still a challenge owing to possible by-product formation. [14][15][16][17] Consequently, the design of an easy, inexpensive and green method of removal of organic dyes from wastewater is an important research area.…”

“…At high initial acid blue 113 concentration, the concentration gradient between the solid liquid interfaces creates more driving force, which leads high initial adsorption rate. The increase of acid blue 113 concentration does not have much influence on the Effect of temperature: During the chemisorption type of adsorption, the quantity of solute uptake increases with increases in temperature [25]. In case of physisorption, the rate of adsorption decreases with increase of temperature.…”

Nanocarbon spheres were prepared from the stems of Alternanthera sessilis. Their characterization studies were performed and the application of nanocarbon spheres for the adsorption of acid blue 113 from the aqueous solution was studied. Effect of pH of effluent, effect of initial acid blue 113 concentration and the effect of solution temperature were analyzed. Pseudo-first order model, pseudo-second order model, Elovich model, Intra-particle diffusion model, Langmuir model, Freundlich model and thermodynamic parameters were used to evaluate the percentage and the amount of acid blue 113 dye removed. The kinetics follows multi-order and Langmuir type of isotherm. The ΔG, ΔH and ΔS parameters which relate to sorption energy were also evaluated. The outcome of the study indicates that nanocarbon sphere is a potential material for the sorption of acid blue 113 with good efficiency.

“…Adsorption kinetics is essential to describe the rate of adsorbate (solute) uptake and helps to determine the time required for reaching equilibrium. Kinetic analysis is also important to evaluate the mass transfer limitation during the adsorption process and provides the most valuable information for the design of adsorption systems [57,58]. In liquid phase systems and porous materials, the course of adsorption of solutes from bulk to pores generally includes the following four consecutive steps:…”

Solution combustion synthesis of calcium aluminate (CaAl 2 O 4 ) nanocomposite using coffee husk extract and its adsorption capacity for removal of Congo red (CR) and Indigo carmine (IC) are reported. Physiochemical properties of adsorbent were studied by PXRD, SEM, TEM and point of zero charge. Batch adsorption studies were conducted to study the effect of adsorbent dosage, pH, contact time, initial dye concentration and temperature on adsorption efficiency of coffee husk derived calcium aluminate nanocomposite (CHCA). Among the isotherms used, Langmuir model explained best the equilibrium data and the maximum monolayer adsorption capacity was found to be 377 and 135 mg/g for CR and IC, respectively. Mass transfer analysis indicated adsorptive removal of dyes was controlled by both external and internal diffusion. Pseudo-first-order model fitted best with experimental kinetic data and adsorption efficiency increased with an increase in the initial bulk concentration of CR and IC. Thermodynamic analysis indicated that adsorption of CR and IC on CHCA is feasible, spontaneous and exothermic in nature. The magnitude of enthalpy and heat of adsorption suggested that the adsorption is physical in nature. The present study explores the potential of coffee husk extract, an agro-based bio-waste, as a novel and eco-friendly fuel in the synthesis of CHCA and the synthesised nanocomposite as a potential adsorbent for the removal of synthetic dyes.
