Adsorption capability of brewed tea waste in waters containing toxic lead (II), cadmium (II), nickel (II), and zinc (II) heavy metal ions
Recently, the search for low-cost eco-friendly adsorbents has become one of the main
objectives of researchers. The aim of this study was to test the removal of four heavy metals,
namely lead (Pb), zinc (Zn), nickel (Ni) and cadmium (Cd), from a simulated watery solution
using brewed tea waste as a potentially suitable adsorbent. The effects of pH levels (2.0–
6.0), adsorbent amount (0.1–5.0 g), contact times (1–150 min.) were examined throughout
the adsorption process. The results of the experiments showed that the heavy metals …
