Adsorption Technique for Heavy Metals

Adsorption switched by catalysis (catalysis switchable adsorption) is a high-efficient treatment technique for wastewater laden with heavy metals, due to the excellent technical applicability and cost-effectiveness. The purification system is filled with the KL-serial adsorbent, a highly effective, low-cost adsorbent manufactured through a remarkable surface modification procedure.

The purification system has been designed to the removal of heavy metals from metal-contaminated wastewater, such as Arsenic (As), Mercury (Hg), Cadmium (Cd), Chromium (Cr), Lead (Pb), Selenium (Se), Thallium (Tl), Copper (Cu), Zinc (Zn), Molybdenum (Mo), Nickel (Ni) and so on. The system has been proved to be high efficient to treat inorganic effluent with metal concentration level ranging from 0.1 to 10 mg/L. To pretreat the relatively high-concentrated metal wastewater, a powerful and environment-friendly agent has been also developed.
