Review An overview of the modification methods of activated carbon for its water treatment …
Various researchers also prepared and applied modified forms of activated carbons in the application of metal enrichment and water treatment. Activated carbons functionalized with pyrocatechol violet [129], 1,2-cyclohexanediondioxime [130], bis-salicyl-aldehyde-1,3-propan-diimine (BSPDI) [131], tartrazine [132], 1,10-phenanthroline [133], …
Heat Treatment as a Food Preservation Technique
The degree of heat treatment required to pasteurize a food is determined by the acidic nature of the food and targeted heat-resistant enzymes or pathogens. In low acid-food like Milk, the degree of pasteurization is based on a 12D reduction in the number of pathogens ( Brucella abortis, Mycobacterium tuberculosis, and Coxiella burnetti) .
