“…Furthermore, the activated charcoal of pecan shells treated with sodium dodecyl sulfate was efficient in the removal of methylene blue in aqueous solution, allowing the use of these residues as raw material for cost-effective and sustainable charcoal production [37]. These wastes are also efficient in removing up to 100% of the iron present in contaminated water over a surface area of 1516.5 m 2 /g and a volume of 0.7 cm 3 /g [38]. Also, experiments referent to the economic evaluation to obtain activated carbons from pecan shells were performed and about 1370 kg of steamactivated and 2964 kg of acid-activated pecan shell carbon could be produced everyday with low costs (U$S 18/h and U$S 2.72/kg) [39].…”

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.

“…Activated carbon treated with sodium dodecyl sulfate (Shawabkeh and Abu-Nameh 2007) was used as adsorption material for the removal of phenol and methylene blue from aqueous solution, and the adsorption capacity was proven to be very high. Surface modification method using surfactants such as sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, or dioctyl sulfosuccinate sodium (i.e., impregnation and addition) can significantly enhance the capacities of activated carbons to remove Cd(II) Ahn, Kim, et al 2009).…”

A novel absorbent was prepared by sodium dodecyl sulfonate (SDS)-modified activated carbon (SDS-AC) and was employed as the microcolumn packing material for separation/preconcentration of trace Cd(II). The method based on Cd(II) was quantitatively retained by SDS-AC sorbent, which entailed cation exchange nature and negative charged surface, facilitating favorable retention of positively charged ions. The retained Cd(II) was effectively recovered with elution by 1 mol Á L À1 HNO 3 , and the eluent was quantified by electrothermal atomic absorption spectrometry (ET-AAS). Under the optimized conditions, the limit of detection (LOD) for Cd(II) was 3 ng Á L À1 with the consumption of 20.0 mL sample solution. The relative standard deviation (RSD) for ten replicate measurements of 50 ng Á L À1 Cd(II) was 2.9%. The developed technique was demonstrated for the determination of trace Cd(II) in water samples and the recoveries for spiked samples were found to be in the range of 94.9-107.2%. For validation, two certified reference materials of water samples (GBW08607 and GBW08608) were analyzed, and the results obtained were in good agreement with the certified values.

“…The adsorption capacity of AC depends on various factors such as surface area, pore size distribution, and surface functional groups of adsorbent; polarity, solubility, and molecule size of adsorbate; solution pH and the presence of other ions in solution, etc. [13][14][15][16][17][18] The drawback of some organic pesticides such as thiram is their low water solubility thus their limited solubility properties cause to limited applications, for example, difficulties of their removal from soil. In this study we have tried to explore that micellar solubilization might be powerful alternative due to their aggregation behavior in aqueous environment for removal processes of hydrophobic pesticides.…”

The solubilization of thiram was studied in micellar solutions of two surfactants possessing the same hydrocarbon tail but different hydrophilic head groups, namely sodium dodecyl sulfate and dodecyltrimethylammonium bromide. Conductivity, spectrophotometry, and surface tension measurements have been used in quantitative analysis of the interaction between thiram and surfactants. In this work the adsorption of thiram onto selected two different activated carbons has been also studied in the absence and presence of micelles. The interaction of thiram in different micellar solutions provided information about the characteristics of adsorption properties of poorly soluble pesticide thiram onto activated carbon in the presence of micelles.
