Web13 apr. 2024 · The adsorption of Pb(II), Cd(II), Zn(II), and Co(II) ions on PVA-CS/CE composite hydrogel was measured at pH 3–9 (Figure 7a). Removal of Pb(II) and Cd(II) was increased upon increasing the initial pH of the solution from 3 to 6, and maximum removal of Pb(II) and Cd(II) was observed at pH 6. Conversely, the maximum removal of Zn ... WebZinc is essential for all living things, forming the active site in over 20 metallo-enzymes. The average human body contains about 2.5 grams and takes in about 15 milligrams per day. Some foods have above average levels of zinc, including herring, beef, lamb, sunflower seeds and cheese. Zinc can be carcinogenic in excess.
