Eliminating herbicides from water. A potentially harmful herbicide can be removed from water with high efficiency using a method developed by scientists in the United States.

James Economy at the University of Illinois, Urbana-Champaign, United States, and his colleagues have created a chemically activated fibers that acts as a filter to remove atrazine from water.

Atrazine, one of the most widely used herbicides in the United States, is found in drinking water contained in the country. Although the effect on humans is not known, James Economy says this substance is a potential carcinogen and may disrupt the normal production of hormones. Environmental Protection Agencies (EPA) United States has set a maximum contaminant level for only 3 parts per billion (ppb) for drinking water.

According to James Economy, the removal of atrazine from water is very essential, not only in the United States but also in other countries like China. It is important to eliminate these toxic materials from water-surface water arising from herbicides shipment of plantation land, he explained.

Currently the water treatment method is best use of activated carbons - porous materials with very high surface area - which absorb atrazine. However, it is known that the pore size of activated carbon can have a powerful effect on the ability of activated carbon to absorb atrazine, and that organic matter can block the pores.

James Economy makes a fibrous form of activated carbon. These are made by coating a glass fiber with a polymer resin together with a catalyst for activate. Fibrous filters are then assembled into a cartridge to be used. He found that the system is more efficient in removing atrazine from water to levels below 3 ppb is recommended rather than granular activated carbons are available in the market. That’s about eliminating herbicides from water.
