“…The Langmuir model was the best model for the biosorption of Cibacron Blue by inactive mycelial biomass of Panus fulvus [28] while both the Langmuir and Freundlich models were found to be the best for Cibacron Blue sorption by activated sludge [29]. The sorption kinetics reported in this study were within the range of published literature for sorption of Cibacron Blue [12,[28][29][30][31].…”

Biosorption is a sort of sorption technology in which the sorbent is a substance that is biologically sourced. In today's world, biosorption is seen as a simple, inexpensive, and ecologically friendly way for removing pollutants from the environment. One of the branches of bioremediation that is utilised to decrease environmental pollution in the context of minimising improper textile waste disposal is this method. The sorption isotherm of Cibacron Blue onto bean peel were analyzed using ten models—Henry, Langmuir, Dubinin-Radushkevich, Freundlich, BET, Toth, Sips, Fritz-Schlunder IV, Baudu and Fritz-Schlunder V, and fitted using non-linear regression. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), BIC and HQC showed that the Freundlich model was the best model in terms of overall best criteria. The calculated evidence ratio was 8 with an AICc probability value of 0.89 indicating that the best model was at least 8 times better than the nearest best model, which was Sips. The calculated Freundlich parameters KF (Freundlich isotherm constant) and nF (Freundlich exponent) were 5.369 (L/g) (95% confidence interval from 4.359 to 6.379) and 3.125 (95% confidence interval from 2.717 to 3.533). The Langmuir constant was utilized to calculate the maximum adsorption capacity QmL (mg/g) which gave a value of 27.83 mg/g (95% confidence interval from 23.69 to 31.98). The nonlinear regression method allows for the parameter values to be represented in the 95% confidence interval range which can better allow comparison with published results.

“…About 80% of the colourant is left on the fabric after dyeing, while the remaining 20% is flushed away as effluent. Around 22% of all industrial wastewater in the United States is generated in the textile industry, according to that industry [4].…”

“…Buyers generally search for common product features including great optical fixation, abruptness, and cleanliness both during the initial purchasing process and after long-term use. Fibre dyes must have a high degree of consistency in colour and be resistant to fading as well as being reasonably priced [1][2][3][4]. The various stages of advanced dyeing technology are selected for use in supplies based on the origin of the fibre and the properties of the dyes and pigments, such as chemical constitution, group, commercial affordability, adhesive matters consistent with the desired substance to be coloured, and financial considerations.…”

An example of biosorption is when the sorbent is made from a biodegradable material. Biosorption is now being seen as a simple, cost-effective, and environmentally acceptable alternative to traditional pollution treatment methods. Bioremediation is one of the branches of bioremediation that is used to minimise pollution in the context of incorrect dye waste disposal. The sorption isotherm of Ethyl Violet onto graphene oxide were analyzed using three models—pseudo-1st, pseudo-2nd and Elovich, and fitted using non-linear regression. Statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), Bayesian Information Criterion (BIC) and Hannan–Quinn information criterion (HQC) that showed that the pseudo-second-order model was the best which was the same finding from the original published work. The calculated evidence ratio was 11 with an AICc probability value of 0.91 indicating that the best model was at least 11 times better than the nearest best model, which was pseudo-1st. Further analysis is needed to provide proof for the mechanism usually tied to this kinetic. Nonlinear regression analysis using the pseudo-2nd order model for the highest concentration tested, which was 10 mM, gave values of equilibrium sorption capacity qe of 30.928 mg/g (95% confidence interval from 29.328 to 32.527) and a value of the pseudo-2nd-order rate constant, k2 of 0.020 (95% confidence interval from 0.011 to 0.028).

“…Phytoremediation technology is the best suitable, accepted as natural and sustainable development strategies to change over contaminated areas into the fruitful one with use of different varieties of plants. In literature, aquatic plant species such as Azolla pinnata (Al-Baldawi et al 2018), Chara vulgaris Mahajan and Kaushal 2020), Lemna minor (Imron et al 2019), Eichhornia crassipes (Tan et al 2016;Sharma et al 2021), Pistia stratiotes Ekanayake et al 2021), Salvinia molesta (Kaushal and Mahajan, 2015;Al-Baldawi et al 2020), Typha angustifolia (Chandanshive et al 2017) are more focussed for the phytoremediation of dye wastewater due to their easy administration in aqueous form. Many terrestrial plants also proved their potential for dye removal due to the effective enzymatic system in their roots.…”

Phytoremediation developed as a green-clean, solar-driven and innovative technique for the eradication of contaminants from the environment from last two decades. In the present research work, phytoremediation potential of an ornamental plant Trachyspermum ammi L. (T. ammi) was examined for the removal of a triarylmethane-Methylene blue (MB) and di-azo-Congo red (CR) dye. The various parameters such as initial dye concentration, contact time, and pH were focused to explore the dye removal capability of T. ammi. The increase in initial dye concentration affects the decolorization potential of the T. ammi. The decolorization potential of T. ammi found to be reduced with enhancing the initial dye concentration of both the dyes. The plant achieved condition of equilibrium after the 40 h of contact time with both MB and CR dye. The favorable pH for T. ammi for the MB dye was observed as 5 while for CR dye was 6. The kinetics of phytoremediation reaction with both MB and CR dyes were studied with help of pseudo-first order, pseudo-second order, and Elovich models and the results were well appropriated to pseudo-first order with the correlation value R2 ≥ 0.95 for MB and R2 ≥ 0.97 for CR. The Langmuir and Freundlich isotherms studies of phytoremediation reaction found in favor of Freundlich equilibrium isotherm with correlation R2 ≥ 0.99 for both MB and CR dyes. The mechanism of T. ammi for removal of dyes was supported with the help of analytical techniques such as Fourier Transform-Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM).
