Compared with Chinese ,ink,, it is more widely available, and its fabrication process is more convenient, simply involving the mixture of tannic acids (TAs) and iron salts. TA is a natural polyphenol extracted from plants, which can chelate with metal ions to form cross-linked complexes in aqueous solution.

An ,acidic, medium is preferred for the decomposition of dyes using Fenton reagent [215,216]. The activity of Fenton reagent is reduced at higher pH due to the formation of relatively inactive iron oxohydroxides and ferric hydroxide ,precipitates, [214,215,216], while a reaction medium with a highly ,acidic, pH is also considered inefficient .

Soluble heavy metal ions are converted to relatively insoluble metal-hydroxide ,precipitates, by adding an alkali-precipitating agent Treated and Removed by adjusting the pH of ,wastewater, to reduce the solubility of dissolved metals Metal precipitation is primarily dependent upon two factors: a. The concentration of the metal, b. The pH of the water.

27/9/2002, · The anti- and prooxidative properties of gallic acid in Fenton-type systems containing H2O2 and Fe(III) were examined in pH 3−10 reaction media and at reaction temperatures of 20−50 °C. Although it is a free radical scavenger, gallic acid may exhibit prooxidative properties, as it promotes the production of hydroxyl radicals due to iron chelation. The overall effect is prooxidative if the ...
