“…Our research school is the first to report the use of NIS as filler material in the fabrication of thermoplastic and thermoset composites [33,[54][55][56][57][58][59][60]65] and for the use as effective adsorbents for remediation of Congo red, methylene blue and ethidium bromide dyes [32,53,64]. Despite myriad research papers reported the use of low-cost agriculture waste as biosorbent for the remediation of toxic dyes; very limited information is available about the use of dye adsorbed biosorbent commonly known as "sludge".…”

First-ever study was done using a low-cost Tribulus terrestris spent, a by-product of a nutraceutical industry as an effective biosorbent for removing acid blue 113 (AB113) from aqueous media. The effect of various factors such as pH, dye concentration, amount of adsorbent, particle size of adsorbent, contact time as also temperature on adsorption have been studied. Analysis of equilibrium data was done by using two number of two-parameter and six number of threeparameter isotherm models. Kinetic studies on adsorption were done using models like pseudo-first order and pseudosecond order. Webber-Morris and Dumwald-Wagner diffusion models helped to study diffusion. Determination and evaluation were also done for change in enthalpy (ΔH°), entropy (ΔS°), and Gibbs free energy (ΔG°) of adsorption system. Scanning electron microscopy, Fourier transform infrared spectroscopy and determination of point of zero-charge were carried out for surface characterization of the adsorbent. We have used a two-level fractional factorial experimental design approach and subsequently analysis of variance to define a statistically developed model from which we obtained values of above parameters which yielded maximum possible adsorption as 93.00 mg/g. The investigations proved that nutraceutical industrial T. terrestris spent is both cost-effective and an efficient biosorbent for the remediation of AB113 dye from aqueous system and textile industrial effluent.

“…After the soaking process, the scales were carbonised at 450–750°C for 60–180 min. The resulted activated carbon was then subjected to thermal treatment using a flash pyrolysis technique at 600°C in a fluidisation chamber flowing upward in a vertical direction under low‐pressure application [28]. The obtained sample was continuously washed using de‐ionised water until the supernatant reaches the neutral pH of 7.0.…”

The extensive discomfort in the expulsion of toxic pollutants even at mild concentrations has demanded the need for prompt methods for the evacuation of dyes and heavy metals. The effective method for depuration of dye from the effluent is by sorption. Chitosan is a bio-polymer which is gaining an increasing interest as one of the sorbents. It was obtained from the crab shells by undergoing several chemical processes and used as an adsorbent for dye, metal removal and also for pharmaceutical purposes. Cross linking it with other co polymers will increase the capacity of adsorption to a maximum level. Fish scales are considered to be a major waste in the food industry and since it takes a long time for decomposing it is considered to be one of the pollutants. Hence it is utilised by converting it into activated carbon by preliminary treatment and into a muffle furnace. The obtained activated carbon is combined with chitosan by using a cross linker and utilised for adsorption mechanism. To analyse the effect of chitosan cross linked with activated carbon obtained from fish scales in adsorption of dye Reactive Blue 9 (RB9) to evaluate the adsorption studies, kinetics, mass transfer studies, thermodynamics of the bio adsorbent.

The present study reports about the use of fenugreek seed spent as a new and efficient biosorbent for the removal of acid blue 113 dye from aqueous media and textile industrial effluent. The spent is a low-cost by-product of nutraceutical industry. The effects of various process parameters of adsorption, such as pH, initial dye concentration, adsorbent dose, adsorbent particle size, contact time and temperature onto nutraceutical industrial fenugreek seed spent (NIFGS) have been studied. Four numbers of two-parameter and six numbers of three-parameter isotherm models were used in the analysis of adsorption equilibrium data. Kinetic studies data conformed to pseudo-second-order model. Molecular diffusion studies were carried out using Weber-Morris, Dumwald-Wagner and film diffusion models. Change in enthalpy (ΔH°), entropy change (ΔS°) and Gibbs free energy change (ΔG°) of adsorption system indicated that the process is physisorption. Scanning electron microscopy, Fourier transform infrared spectroscopy and point of zero charge were used in characterizing the adsorbent. Fractional factorial experimental design and analysis of variance along with statistically developed model for adsorption helped to predict for a maximum adsorption of 661.5 mg g −1 using NIFGS. Application of NIFGS to textile industrial effluent and scaling up of the experimental process by three orders gave encouraging results.
