Structural properties of graphene-oxide and its capacity for the elimination of dimethoate from water
Апстракт
Organophosphate pesticides are known to be some of the most toxic substances synthesized by a man today. Extensive use of this group of compounds in contemporary agriculture results in a critical need for their efficient removal from the environment, especially water. Adsorption of pesticides on different materials is one of the most frequently used strategies for this purpose. In the past decade, the use of graphene-oxide escalated due to its interesting properties. In this contribution, the adsorption of organophosphate pesticide dimethoate on two commercially available graphene-oxides has been investigated. The materials were characterized by different physico-chemical methods. Careful structural characterization of adsorbents was combined with batch adsorption experiments. It was shown that 1 g of both graphene-oxides is capable of adsorbing 9×10-3 mol dm-3 of dimethoate at 25 °C. A satisfactory agreement of both sets of experimental results with the Langmuir isotherm model suggest...s the monolayer adsorption on the homogenous surface. The adsorption was also investigated at 30 and 35 °C. The results showed that the concentration of adsorbed dimethoate increases with temperature for both studied adsorbents. Investigated grapheneoxides were successfully used for the removal of dimethoate from water.
