“…The ∆G° values of thiram adsorption were -1.87 and -3.35 kJ mol -1 in Inceptisols and Ultisols, respectively. The negative ∆G° values indicate that the H bonds were the main interaction in the adsorption process in the soil (Li et al, 2011). This finding is in line with that of Zahoor (2010), who obtained negative ∆G° values for thiram adsorption onto activated C at various temperature levels.…”

The present study was conducted in order to investigate the adsorption and desorption behavior of tetramethylthiuram disulfide (thiram) using the batch equilibration technique in two soil namely: Ultisols and Inceptisols. The adsorptiondesorption isotherms were expressed by the Freundlich equation. The adsorption isotherms of thiram was classified as L-type under Gile's classification. The Freundlich's adsorption coefficient (Kd) value for thiram in the Ultisols and Inceptisols soil were 3.78 and 2.10 mL g -1 , respectively. Results indicated that soil organic matter was the main factor affecting thiram behavior in the studied soils. The calculated total percentage desorption values from the Ultisols and Inceptisols soil after the fourth desorption process were 39.2% and 51.6%, respectively. The negative Gibb's free energy change (∆G°) values obtained suggest that thiram adsorption is an exothermic process. The effects of temperature (25, 30, and 35 °C) and soil pH (3, 7, 10) were also studied on adsorption of thiram in the test soils. Results showed that adsorption of thiram was not affected by temperature but clearly affected by soil pH.Key words: Thiram, adsorption, desorption, soil, temperature, pH.

“…Adsorption-desorption isotherms are usually described by linear models and/or Freundlich models. It has been shown that sorption-desorption capacity of pesticides in soils depend on the type of soil, temperature, pH and properties of pesticide itself (Ismail and Maznah, 2006;Cao et al, 2008;Li et al, 2011).…”

“…Adsorption of pesticides is less in alkaline than in acidic soils; however, at quite low and high pH, the adsorption decreases due to change in the clay mineralogy (Edwards 1975;Kumar and Philip 2006;Li et al 2011).

Pulse polarographic determination of thiophanate methyl fungicide in relation to its soil adsorption study

Background: The environmental pollution caused by the extensive use of the pesticide thiophanate methyl is of great concern, because it is a category III acute toxicant and a suspected carcinogen. Method: A remarkably sensitive differential pulse polarographic method for the determination of thiophanate methyl has been developed. The method is based on the reaction of the fungicide with copper(II) perchlorate in the presence of butylmethylimidazolium bromide (ionic liquid) in acetonitrile. Results: The reaction product exhibits an analytical useful diffusion controlled peak at −180 mV (vs SCE), and the thiophanate methyl has been determined in the linearity range 1.25 × 10 −6 to 12.5 × 10 −6 mol L

“…Pesticides could be adsorbed by different soil components such as organic matter (Farahani et al 2008), clays (Sharma and Awasthi 1997), carbonates and oxy-hydroxides (Stathi et al 2011) and even rock fragments (Vischetti et al 2010). Also adsorption and desorption processes could be influenced by other soil characteristics such as pH (Stathi et al 2011) and temperature (Li et al 2011). The adsorption and desorption of pesticides could have different effects on pesticide persistence in the soil.…”

In the present work, different methods were tested to evaluate the adsorption and desorption of metalaxyl in two acid soils with different organic carbon and clay contents. The three methods (batch, stirred flow chamber and column) that were examined produced similar findings when the two soils were compared: (a) the metalaxyl adsorption capacity was higher in the soil with higher organic matter and clay content, and (b) the soil with the lower organic matter and clay contents provided higher adsorption rate constants. In the two soils tested, the metalaxyl adsorbed in the soil was highly reversible. When only one soil was considered, the different methods yielded different results. The metalaxyl adsorption and its rate were higher with the stirred flow chamber than in the column experiments, and in the column experiments, the total metalaxyl adsorption and the rate of adsorption were higher than in the batch experiments. The percentages of metalaxyl desorbed from the soil were similar in the stirred flow chamber and column experiments, but in the batch experiments, the percentages were significantly lower. In the stirred flow chamber experiments, the desorption processes were faster than the adsorption processes, while in the column experiments, the adsorption and desorption processes exhibited similar rates.
