ZnO nanopowder for water treatment/purification:
Advantages: The preparation process is simple, the cost is relatively low, and the degradation efficiency is higher, making zinc oxide nanoparticle a suitable choice for large-scale degradation of organic wastewater.
Using ultraviolet light or sunlight as the excitation source to degrade pollutants in water, including difficult-to-biodegradable organic pollutants and advanced treatment of drinking water, has a good development prospect in the field of water treatment, and has become the current hotspot for maintenance of ecological balance and environmental protection.
Nano ZnO photocatalysis treatment of difficult-to-biodegradable organic pollutants:
1. As a new type of photocatalyst, nano-zinc oxide has relatively small electron effective mass, higher electron transfer shelter, and lower charge recombination rate. It can absorb sunlight in a wider range. Zinc oxide nanoparticle has stronger absorption of light below 400nm, and is more suitable for providing efficient driving force for the reduction and oxidation process of chemical reaction systems under sunlight, and is used for photocatalytic degradation of organic pollutants in water.
2. Nano zinc oxide(ZnO) can be used for printing and dyeing wastewater, phenols, and other organic matter.
3. ZnO nano powder photocatalysis treatment of micro-pollutants in drinking water: Using ZnO nano photocatalytic technology to deeply purify drinking water, the excited electrons directly participate in the degradation process, and its specific surface area also produces a large amount of hydroxyl radicals due to the adsorption of water, which gradually degrades harmful substances, and finally mineralizes to CO2 and H2O. Simple Inorganic. In addition to organic matter, it also has a good removal effect on bacteria, viruses and some toxic inorganic substances.
