Abstract

The feasibility of atrazine degradation with nano zero valent iron and it is comparison with iron powder was investigated. The experimental design was factorial with completely random design. Studied Factors were two types of soils, acidic and non-acidic, two types of iron powder, micro-and nano-scale at four concentrations, 0, 1, 2 and 5 grams in 100 grams of soil contaminated by 30 mg of atrazine. Sampling intervals were one day, one week and two weeks. After extraction of atrazine the concentration was measured by HPLC and data were analyzed by Mstatc software. The result showed that the main factors (Iron type, concentration and soil type) caused a significant difference. Although both types of micro-and nano iron powder were able to remediate atrazine in soil, but the differences between these two treatments was significant and the rate of decomposition by nano iron powder was higher. Atrazine degradation with zero valent iron nano particles was higher in acidic soil. The highest degradation rate was belonging to treatment with 5 grams of nano scale iron and the lowest observation was the control with no iron powder in non-acidic soil. It is concluded that the use of nano zero valent iron for atrazine degradation, especially in acidic soils is promising.
