“…This is because of the fact of active adsorbent sites with the further increase in dosage exhibit less uptake of IC due to saturation or overlapping of active sites. These results are in agreement with others [36][37][38].…”

The present work determines efficiency of domestic food waste like tea waste in removing indigo carmine from synthetic textile wastewater. Carbonaceous material (tea waste) has been employed and it showed removal percentage of indigo carmine at 90% through adsorption process. Carbonaceous material was chemically activated by using modified Hummer’s method and it was observed through Scanning Electron Microscopic image, Fourier Transform Infrared Spectrometer, X-ray diffractometer and Brunauer, Emmett and Teller analysis that revealed that the modified biochar is comparably similar to graphene oxide (GO). Various experimental parameters are evaluated for the removal efficiency of the synthesized adsorbent under the present study. Results of the experiments performed using the GO-like adsorbent synthesized from tea waste confirmed potential efficiency of adsorption of indigo carmine dye from synthetic waste water solution. The adsorption mechanism has been analysed by fitting the experimental data in different adsorption isotherm and kinetic models. The results indicated that the adsorption followed Langmuir isotherm model with maximum uptake of 20 mg g− 1 and pseudo second order kinetic model with the best correlation coefficient. The thermodynamic study showed the dye removal to be spontaneous and endothermic.

“…As shown in Table 4, the 1/n value of 0.8887 obtained from the slope of the Freundlich plot was greater than 0.5, indicating favorable multilayer adsorption on heterogeneous surfaces [24]. Table 5 compares IC maximum adsorption capacities (q m ) with different adsorbents reported in the literature [25][26][27][28]. The BP adsorbent synthesized here revealed high potential in comparison with the other adsorbents.…”

This study investigated the preparation method and adsorption efficiency of porous adsorbents prepared from banana peels (BP) waste. The BP waste was acquired from banana fried chip factories in Sukhothai province. Chemical activation by sulfuric acid was used to activate the raw material, followed by carbonization at 500 °C. The activated BP adsorbent has been characterized by energy dispersive X-ray spectrometer (EDXRF), N2 adsorption-desorption isotherms (BET), scanning electron microscopy (SEM), and zeta potential measurements. The analysis of chemical properties showed that it mainly contained 70.39 % K matter. The specific surface area of the BP sample reached 215.05 m2/g under acid activation and thermal treatment. The SEM images showed the morphologies of the BP adsorbent before and after activation. There was a significant change in the morphology and in the dried BP and activated BP. The pHPZC value of the activated BP obtained under optimal conditions was 4.13. Adsorption of indigo carmine (IC) onto porous activated BP at different initial IC concentrations (10 - 100 mg/L) and contact times (30 - 120 min) was investigated using batch experiments (0.1 g/50 mL). At an optimum contact time of 60 min, maximum adsorption capacity was determined at 56.18 mg/g. The Freundlich isotherm model with a high correlation coefficient was used to describe multilayer adsorption. The kinetic study fit well with a pseudo second-order kinetic model that represented chemisorption. The negative deltaG° value of –14.64 kJ/mol indicated that adsorption of IC onto the BP adsorbent was spontaneous in nature at 305.15 K. HIGHLIGHTS Increase the value of the biomass resources was produced form banana peels as high surface area adsorbent The qmaxfor indigo carmine (IC) adsorption was 56.18 mg/g under optimized conditions The adsorption of the IC follows the Freundlich model and pseudo-second order kinetic model Negative deltaG° value indicated the possibility of IC adsorption process GRAPHICAL ABSTRACT

“…In recent years, investigators around the world have researched the treatment and utilization of red mud. These investigations mostly focused on utilizing the red mud to produce building materials (such as bricks, novel inorganic polymer paving blocks, cement, concrete, glass, and ceramics) [5][6][7][8][9][10][11][12], recover valuable elements [13,14], purify gas [15], treat water [16], and improve soil [17]. The building materials industry has been very interested in the treatment and utilization of red mud, because it can be cost effective.…”

In this work, related performances of asphalt binders with Bayer red mud powder (RMP) were studied. RMP replaced the traditional limestone powder (LSP) as a filler in asphalt binder. The replacement rates were 0%, 25%, 50%, 75%, and 100%, respectively. In this study, seven F/A (filler-to-asphalt, weight/weight) ratios for each of the fillers were selected: 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, and 2.1. Penetration, softening point, rotational viscosity (RV), dynamic shear rheometry (DSR), and bending beam rheometry (BBR) tests were used to evaluate the properties of the asphalt binder. Penetration into the asphalt binder decreases linearly with increasing F/A ratio. Moreover, penetration of binder with RMP is lower than that of asphalt binder with LSP (RMP0), and among the five fillers tested, RMP100 showed most significant influence on penetration of the asphalt binder. The addition of RMP increases the softening point of the binder. DSR results show that the improvement in the high temperature performance is most significant after replacing 75% of the LSP with Bayer RMP. BBR results show that with increasing substitution of RMP for LSP, the creep stiffness (S) increased while the rate of change of S (m-value) declined. The low temperature performance of every asphalt binder was not enough to meet the Superpave requirements. In order to meet the Superpave requirements for S and m-values, the maximum F/A ratios of the five replacements corresponding to the fillers with 0%, 25%, 50%, 75%, and 100% RMP, were 1.3, 1.2, 1.1, 1.0 and 0.9, respectively. At 135 • C, rotational viscosity showed that RMP75 and RMP100 with a maximum F/A ratio of 1.1 are the best choices for asphalt binders, considering economic and construction requirements.
