“…This accounted for the reason why we selected 0.1 g of CS for the adsorption study to ensure optimum use of the adsorption sites. A similar trend was also documented by other researchers in the removal of heavy metals (Abdus-Salam and Adekola 2018; Bayuo et al 2019;Ozsin et al 2019), and dyes (Terangpi and Chakraborty 2016;Uddin et al 2017) from polluted water.…”

The toxic effects of anionic dyes such as tartrazine and sunset yellow on humans and the aquatic environment are of serious concern. The need for the removal of these dyes from wastewaters led to the use of adsorption techniques as a cheap and efficient treatment method. Thus, this research was based on the preparation of a low-cost activated carbon derived from cassava sievate designated as CS, which was utilized in the adsorption of sunset yellow and tartrazine from simulated wastewater. The sorption process was carried out under varying process factors in a batch mode. Adsorbent characterization displayed the presence of surface functional groups by the FT-IR and a porous structure as revealed by scanning electron microscopy. Optimum dye uptake was recorded at pH (1.0–2.0), temperature (30–40 °C), CS dosage (0.1 g), and dye concentration (150 mg/L). A maximum CS monolayer uptake of 20.83 and 0.091 mg/g was recorded for tartrazine and sunset yellow dyes, respectively. The pseudo-second-order (R2 > 0.99) and Freundlich (R2 > 0.92) models were most fitted to the kinetics and isotherm data of the uptake of the dyes on CS. The adsorption equilibrium attainment was reached was within 90 min of dye sequestration. The experimental results revealed that both sunset yellow and tartrazine dyes were considerably adsorbed onto the environmentally compatible and low-cost activated carbon derived from cassava sievate.

“…The results illustrate that, HSOD has a very small specific surface area 2.35 (m 2 /g) compared to the surface area of SSOD 27.29 (m 2 /g), this shows that synthesis via topotactic conversion produces significantly enhanced specific surface area. The larger specific surface area implies increased adsorption capacity, hence more particles from wastewater may be trapped on the surface of the SSOD than HSOD [ 31 , 32 ]. SSOD has larger pore volume than HSOD implying that SSOD has more accessible pores than HSOD.…”

Phenol is regarded as a major pollutant, as the toxicity levels are in the range of 9–25 mg/L for aquatic life and humans. This study embedded silica sodalite (SSOD) and hydroxy sodalite (HSOD) nanoparticles into polysulfone (PSF) for enhancement of its physicochemical properties for treatment of phenol-containing wastewater. The pure polysulfone membranes and sodalite-infused membranes were synthesized via phase inversion. To check the surface morphology, surface hydrophilicity, surface functionality, surface roughness and measure the mechanical properties of the membranes, characterization techniques such as Scanning Electron Microscope (SEM), contact angle measurements, Fourier Transform Infrared, Atomic Force Microscopy (AFM) nanotensile tests were used, respectively. The morphology of the composite membranes showed incorporation of the sodalite crystals decreased the membrane porosity. The results obtained showed the highest contact angle of 83.81° for pure PSF as compared to that of the composite membranes. The composite membranes with 10 wt.% HSOD/PSF and 10 wt.% SSOD/PSF showed mechanical enhancement as indicated by a 20.96% and 19.69% increase in ultimate tensile strength, respectively compared to pure PSF. The performance evaluation of the membranes was done using a dead-end filtration cell at varied feed pressure. Synthetic phenol-containing wastewater was prepared by dissolving one gram of phenol crystals in 1 L of deionized water and used in this study. Results showed higher flux for sodalite infused membranes than pure PSF for both pure and phenol-containing water. However, pure PSF showed the highest phenol rejection of 93.55% as compared to 63.65% and 64.75% achieved by 10 wt.% HSOD/PSF and 10 wt.% SSOD/PSF, respectively. The two sodalite infused membranes have shown enhanced mechanical properties and permeability during treatment of phenol in synthetic wastewater.

“…Activated carbon adsorption is an important and efficient technique for removing contaminants from waste residues treatments. Although many materials are explored for the production of activated carbon, raw materials are widely used due to their wide availability in the environment and reduced costs, making them attractive options and sources of raw materials for activated carbon production [34].…”

Considering a large amount of high potential materials coming from the processes to obtaining pecan nut, there are important future perspectives to enable an increase of using pecan materials. For this, structural support and the development of scientific research are needed to reuse the wastes in an environmentally friendly way. Thus, the aim of this scientific research is to present a detailed literature overview regarding the characterization of pecan waste materials, the main applications and technologies used to add value to these materials. The study is fundamentally based on the scientific literature related to obtaining products from pecan wastes and their application in food-related areas. The lack of sufficient data on the proposed theme requires a properly structured approach to provide a clear perspective on the subject and to highlight the current limitations. It is evident that pecan culture has presented a prosperous context with respect to the world and Brazilian production. The scientific literature presented many studies that employ the approach of using remaining pecan materials. Thus, it is clear the range of fields that apply the residuals for the most diverse purposes, which enables them to add value to pecan coproducts.
