General information
- Short Summary
-
Established Slovak scientific and research institutes have developed a highly effective composite sorbent for the removal of contaminants from water for drinking purposes. These are mainly heavy metals such as arsenic, antimony, chromium, cadmium, lead and others. The composite sorbent can be also used in wastewater treatment, including wastewater from chemical and electronic industry.
The preferred cooperation type are commercial agreement or investment agreement. - Full Description
-
Contamination of water is a global problem. Among the most frequently occurring contaminants in water are heavy metals such as arsenic, antimony, cadmium, mercury, chromium ions, nickel, lead and others, as well as waste products from various industrial productions. The presented technology developed by a team of inventors from established Slovak scientific and research institutes represents a highly effective and inexpensive method of removal of such contaminants.
The composite sorbent is prepared by controlled carbonization of fibrous cellulose raw materials which are annually produced in billions of tons by nature (resulting in a significant reduction of production costs of the sorbent). The resulting nanoporous carbon fibers are modified with hydrated iron oxides entrapped in the pores and on the surface of the fibers. The original molecular structure of the sorbent facilitates the achievement of a synergy effect of carbon and iron oxide, and provides not only a high efficiency but also a high rate of contaminant capture. The physical structure of the composite sorbent reduces the resistance to water flow, and its efficiency in removing contaminants is in the area of practical applicability independent from water pH. Main physical properties of nanoporous carbon fibers are length (20 microns to several cm), diameter (10 to 50 microns) and BET surface area (several m2/g to almost 2000 m2/g).
The presented composite sorbent can be used in the treatment of water for drinking purposes, as well as in the treatment of wastewater from chemical and electronic industry. The composite sorbent is significantly more effective than the top commercially available sorbent, often several times. In laboratory tests, residual concentrations of heavy metals were achieved that comply with limits for drinking water.
The institution is looking for a partner to cooperate with via commercial agreement or investment agreement. - Advantages and Innovations
-
• high removal efficiency of heavy metals: arsenic 97.8%, antimony 97.6%, chromium 96.4%, cadmium 88.9%, lead >98.9%,
• low production price achieved by using input raw materials from plant wastes,
• up to 163% more effective than other commercial products, depending on the type of contaminant. - Stage of Development
