“…Further, a value of 0.7696 for 1/n as obtained from Freundlich isotherm clearly indicate a normal Langmuir isotherm and ruled out the possibility of cooperative adsorption 82 . Literature survey reveals that adsorptive decontamination of CV by other adsorbents such as agaricus bisporous 83 , ananas comosus 84 , breadfruit skin 85 , calotropis procera peel 86 , cucumis sativus and cucumis sativus/H 2 SO 4 -modified 87 , eggshell 88 , formosa papaya seed powder 89 , grapefruit peel 71 , jackfruit leaf powder 90 , jalshakti polymer 91 , jute fibre carbon 92 , natural clay mineral 93 , rice husk/NaOH-modified 94 , sawdust 95 , syzygium cumini leaves 96 , tea dust 45 , tomato plant root 97 , water hyacinth 98 has also been observed to follow Langmuir isotherm. The values of isotherm constants of this model as reported for different adsorbents are listed in Table 3 .…”

Present investigation explores the possible reusability of synthetically contaminated wastewater containing crystal violet (CV) organic dye using Tectona grandis sawdust (TGSD) waste as a very low-cost adsorbent. The adsorbent was characterized by proximate, SEM/EDX, FTIR, and XRD analyses. Batch adsorption studies were carried under changing conditions of contact time, the initial concentration of CV, pH, TGSD dose, TGSD particle size, and temperature. The experimental data were tested using Langmuir, Freundlich and Temkin isotherm models, and the data were best followed by Langmuir one. The kinetic results were examined in the light of different models and pseudo-second-order was obtained to be best obeyed. The values of ΔH° (28.642 kJ/mol), ΔG° (-10.776 to -7.080 kJ/mol) and ΔS° (121.8 J/K/mol) in the temperature range of 293–323 K suggested the overall process to be spontaneous, endothermic and associated with an increase in randomness. On the basis of experimental results and their analyses, it has been established that TGSD is one of the most effective adsorbents among those obtained from the domestic, agricultural and industrial wastes. Thus this adsorbent can be effectively utilized to make the impure wastewater reusable.

“…After chemical modification, the dye adsorption was seen to be 97% at 45 minutes for modified Ha as compared to 93% at 45 minutes for modified Cc. e driving forces among the liquid and solid phase help in counteracting of the mass transition resistance among the dye molecules [2,65]. e point of zero-charge pHpzc, where the negative and positive sites are equivalent [67,68], was determined by the electrochemical method [69] as described in our previous studies [27].…”

Holarrhena antidysenterica (Ha) and Citrullus colocynthis (Cc) biowaste from indigenous Pakistan resources was used to remove toxic brilliant green (BG) dye from aqueous solutions in a batch mode. Tartaric acid chemical modification gave promising results than the nonmodified forms of biowaste. Surface characterization was carried out by FT-IR and SEM. The optimum conditions for (BG) dye elimination by Ha-tartaric acid modified (Ha-Ta) were 1.8 g, 45 minutes, 4.0 pH; 40°C, and 100 rpm and with Cc-tartaric acid modified (Cc-Ta) were 1.6 g, 45 minutes, 6.0 pH; 40°C, and 150 rpm dye solution shaking rate, which gave optimum results. Equilibrium data of raw and chemically modified biowaste followed the Langmuir model indicating monolayer chemisorption. Qmax values were found to be 55.24 mg/g, 112.35 mg/g, 50.50 mg/g, and 79.36 mg/g for Ha, Ha-Ta, Cc, and Cc-Ta. Kinetics followed the pseudo-second-order kinetic model. Dye removal involved surface and intraparticle mode of diffusion. Thermodynamic studies proved the process to be spontaneous and exothermic one. The adsorbents can be effectively utilized for the removal of toxic basic dyes, such as BG from wastewaters.

“…Thus, the wasted leaf of these trees could be a suitable option for the biosorption process. So far, these trees have been used to remove pollutants such as malachite green , cadmium , crystal violet, and eosin B . According to the literature survey by the authors, the leaves of S. cumini and P. cineraria have not been used to remove fluoride (F).…”

This study was designed to present a facile and effective biosorbent from Prosopis cineraria and Syzygium cumini leave (PCL and SCL) for fluoride removal. The test was done in batch mode and the effect of contact time (5, 25, 60, 90, and 120 min), initial fluoride concentration level (3, 5, 8, and 12 mg/L), and biosorbent dose (1, 3, 5, 10, and 25 g/L) on the biosorption process were examined. The optimum conditions for the maximum fluoride removal were occurred at 1 g/L biosorbent dose and contact time of 120 (for PCL) and 90 min (for SCL). The results suggested that the pseudo‐second‐order and Langmuir isotherm models described the experimental data well. According to the Langmuir model, the maximum adsorption capacity of fluoride for PCL and SCL was attained 11.52 and 7.4 mg/g, respectively. Based on Boyd and intra‐diffusion models, the biosorption of fluoride onto PCL and SCL was mainly controlled by film‐diffusion. The study revealed the potential use of PCL and SCL as two new effective biosorbents for the removal of fluoride from aqueous solution. © 2019 American Institute of Chemical Engineers Environ Prog, 38: S429–S440, 2019
