LED Lamps Implemented in Removal of Pollutants from Water by Using Nanocatalysts

Tehran, Iran | Posted on July 1st, 2014

The nanocatalyst has been designed in a way that it is able to degrade hazardous pollutants in water in the presence of low-energy lamps with very high efficiency.

The main purpose of the research was to purify water and eliminate toxic pollutants from water by using nanocatalyst technology. To this end, it was tried to simultaneously produce a nanocatalyst in proportion with low severity optical sources, to make applicable use of LED lamps in contact with the produced catalyst, and to purify toxic pollutants in water by using this system.

According to the present report, the use of nanocatalyst increased the efficiency of the removal of diazinon up to 53.2% in comparison with the commercial catalyst of titanium oxide. This nanocatalyst is able to eliminate 96.3% of diazonin from water. It is obvious that the use of LED lamp in the purification system decreases the amount of energy consumption, and it prevents environmental pollutions.

The nanocatalyst is made of composite based on titanium oxide with pre average diameter of about 17 nm and crystals at 6 nm. The increase in the concentration of nanocatalyst boosts the degradation of the pollutant, to the extent that as the concentration increases from 25 to 300 mg/L, the purification yield increases from 48% to 96%.

The researchers are currently working on the production of a catalyst based on zinc oxide, and they are studying its photocatalytic activity in the presence of LED lamp.

Results of the research have been published in Water Research, vol. 59, issue 1, January 2014, pp. 130-144.
