Derivatisation of Cashew Gum by Esterification Using Citric Acid and Glycerol

Design and Fabrication of TiO2/Lignocellulosic Carbon Materials: Relevance of Low‐temperature Sonocrystallization to Photocatalysts Performance

“…The formation of new functional groups (COOH, O=CÀO and C=CÀOH) on the surface of SWP700 was also observed in our previous study [35] where these functional groups favored a better interaction between TiO 2 precursor and SWP700 surface. After the Stage II, it can be seen the initial step of formation of characteristic cross-linking bonds between lignocellulosic carbon materials and citric acid as previously reported, [12][13][14][15][16][17][18][19][20] and also confirmed, in this work by HR-XPS measurements, the presence of C=O (~531.2 eV) and CÀO (5 33.1 eV) on the surface of SWP700 and STARBON-800 which visibility increase further with the treatment steps (Table 3 and 4).

“…Additionally, citric acid has been studied as an "eco-friendly" nonformaldehyde cross-linking agent to improve the physicalchemical properties (bearing hydroxyl and carboxyl groups) of lignocellulosic carbon materials derived from biomass such as chitosan, [12] silk, [13] wool, [14] starch, [15] cashew gum (polysaccharide from natural sources), [16] cotton, [17] cellulose, [18] wood [19] and paper.

[12][13][14][15][16][17][18][19][20] It was established that citric acid is an excellent chelating agent and a suitable precursor that ensures high specific surface area and nanometric particle size. Citric acid can also be used as stabilizing coordination agent sol-gel method as a, which may significantly inhibiting metal ions segregation and making the precursor homogeneous.…”

Extraction and Physicochemical Characterization of <i>Adansonia digitata L.</i> Mucilage

“…characteristic of polysaccharides which may relate to galactorunic acid. (Abdulsamad et al, 2015) and (Saeedi et al, 2013) have reported C=O at this regions for cashew gum and plantago mucilage. ATR-FTIR result as well as elemental analysis indicated the presence of amide groups and nitrogen in ADM.…”

Characterization of Khaya Senegalensis Gum: Effects of Drying Methods on the Physicochemical Properties

“…The presence of carboxylic acids supports the assumption of CO2 evolution as a mechanism of thermal transition of gums in the DSC thermograms 44 . Similarly, the presence of carboxylic acid at 1726 cm-1 frequency in cashew gum was an indication of its presence in cellulose containing compounds 45 . The results of ATR-FTIR corrobrated with elemental analysis as both showed the presence of amide groups.…”
