“…K F (mg g −1 ) is the Freundlich isotherm constant related to the heterogeneity of the biomass surface and its activity as sorbent, the parameter n (g L −1 ) is a measure of the nature and intensity of the biosorption process and its inverse value 1/n (L g −1 ) is known as the heterogeneity factor. This model assumes ▸ that if n is equal to 1, then the linear biosorption occurs and leads to identical adsorption energies for all binding sites; the biosorption is a chemical process for n < 1 and a physical process for n > 1 [70].…”

A low-cost biosorbent obtained from the Palomino Fino grape seed, a Sherry wine industry by-product, has been proposed as a way of valorising this material. The biomass was characterised obtaining values of 0.68 ± 0.05 g mL−1 for bulk density, 1.02 ± 0.09 g mL−1 for apparent density and 33.3% for porosity. The pHpzc was 5.2 and the surface negative charge value was 2.4 ± 0.2 mmol g−1. The analysis of surface morphology showed differences due to the sorption. The results showed a promising potential for chromium(VI) removal from aqueous solutions. The studies were carried out in batch scale and a 23 factorial design was applied for the optimisation of the process. A percentage of 91.7 ± 0.6% was achieved for the biosorption of Cr(VI) under optimal conditions using pH 5.5, 15 g/L of biosorbent and 8 h of contact time. The biosorption capacity showed a remarkable linearity from 0 to 2 mmol L−1 Cr(VI) and a precision of 0.64% for the removal of 1 mmol L−1 of metal. Langmuir, Freundlich and Temkin isotherm equations and the parameters of six kinetic models were used in the equilibrium modelling and identifying the mechanism of the biosorption. The combination of physical and chemical sorption mechanisms was proposed for the chromium removal with a high maximum sorption capacity (qmax = 208.3 mg g−1). Thermodynamic parameters indicated the spontaneous and endothermic nature of the chromium removal. The successful biosorption was based on the special grape seed components with a relevant content in antioxidant and lignocellulosic compounds.

“…Furthermore, cadmium and cadmium compounds were grouped by the IARC as carcinogenic agents to humans (Group 1). It was enacted with less than 0.003 mg/L of cadmium ions in drinking water [ 2 ]. Previous studies have reported that the food chain is the main route of cadmium ions ingested by humans and that it easily accumulates in living organisms because of its non-degradable nature [ 3 , 4 ].…”

“…For material activation, a frequency of 35 kHz is preferable [32][33][34]. Many recent adsorption studies have used reactive adsorbents such as ultrasonicated dragon fruit peel biomass [35], ultrasound pretreated peanut husk powder [36], and ultrasonication modified corn-pith [37]. As ultrasonically treated shells have not been used previously, the ultrasonicated egg shell powder is being investigated in this study for malachite green dye adsorption.…”

The present research focuses on synthesizing surface-modified egg shell powders using ultrasonic modification method for the effective adsorption of malachite green dye (MG). The presence of functional groups and surface morphology of ultrasonic-assisted egg shell powder (UAESP) was characterized using Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscopy (SEM) analysis, respectively. A batch adsorption study was performed to predict the optimum conditions, and the results showed that maximum adsorption rate at the solution pH of 8.0 within the interaction time of 90 min, dosage of 1.5 g/L for MG dye concentration of 25 mg/L, and temperature 30°C. The isotherm and kinetics modeling of the present adsorption system can be well described by Freundlich and pseudosecond-order kinetics, respectively. The monolayer adsorption capacity of UAESP for MG dye was originated to be 64.58 mg/g. The results of the thermodynamic study reported that adsorption removal of MG dye onto UAESP was exothermic and spontaneous. This study accredited that UAESP has higher efficiency, cost-effective, and sustainable adsorbent for the removal of hazardous dyes on an industrial level.
