Abstract
This invention relates to novel adsorbent compositions for adsorbing pesticides like chlorpyrifos and malathion. This composition consists of nanoparticles of gold/silver supported on activated alumina or magnesia in powder or other forms. This invention includes a device and a method for decontaminating water contaminated with pesticides. This device consists of a housing provided with an inlet and an outlet. The housing is loaded with nanoparticles of gold/silver supported on activated magnesia. Contaminated water is allowed to pass through the housing while pesticides are adsorbed by the composition. Decontaminated water flows out through the outlet.
Claims6
Adsorbent compositions for removing pesticides like chlorpyrifos, malathion and other organo halogen/sulphur pesticides comprising gold/silver nanoparticles having a size upto 150 nm deposited on activated alumina and/or magnesia.
A device for decontaminating water contaminated with pesticides like chlorpyrifos, malathion or other organo halogen/sulphur pesticides which comprises a housing loaded with gold/silver nanoparticles having a size upto 150 nm supported on activated alumina and/or magnesia, said housing provided with an inlet connectable to water supply source and an outlet for decontaminated water, said outlet being provided with regulatory means.
A method of decontaminating water by removing pesticides such as chlorpyrifos, malathion or other organo halogen/sulphur pesticides comprising the step of allowing contaminated water to flow through a bed of gold/silver nanoparticles having a size upto 150 nm supported on activated alumina and/or magnesia to adsorb said pesticides and collecting decontaminated water flowing out of said bed.
