Adsorption and Desorption Characteristics of Bispyribac-Sodium Pesticide in Eight Soils in South of Iraq [ READ ]
Layla Balasem Almalike, Anis Al-Najar, Zaki N. Kadhim
Kinetic batch experiments were used to study the adsorption-desorption behavior of bispyribac-sodium (Herbicide, pyrimidinyl oxybenzoic acid) in soils from different locations in south of Iraq, Nasiriya, Amara, and mostly Basrah soils to study their physico-chemical properties which are regarded as responsible for adsorption-desorption properties, such as moisture content, loss on ignition, pH, organic matter contents, particle size distribution, analysis and exchangeable cations and anions. The kinetic study of adsorption processes were performed with four different initial concentrations of each pesticide, 3, 5, 10, and 15 µg ml-1 ( ratio1:10 ). The kinetic experiments were carried out after equilibration for 0.5, 1, 2, 3, 4, 6, 24, 48, and 72 hours for each pesticide. Desorption was evaluated using the samples in the tubes after the adsorption tests.
