Abstract
After treating soils by $Iag, Shale and compost at the rate of 20 mg.g-1 soil, on the adsorption of Zinc in sandy silt soil, sandy soil, silt clay loam soil and silt clay soil which were conducted under laboratory conditions. These soils had received different concentrations of Zn , there was an increase in the equilibrium concentration in this order as follows: Control > slag> shale> Compost. The maximum adsorption of Zn in different soils after treating with soil amendments conformed to both Freundlich isotherm in order: EI Sadat City (sandy silt soil) > Milig Shibin Elkom (Silt clay loamy soil) > Malanta Slovakia R. (Silt loamy soil) > EI Tahrier (Sandy soil), and Langmuir isotherm was formed as follow: Milig Shibin Elkom (Silt clay loamy soil) > EI Sadat City (sandy silt soil) > Malanta Slovakia R. (Silt loamy soil) > EI Tahrier (Sandy soil). The effect of soil treatments on the maximum adsorption means in spit of soil types can be arranged in the following order: Compost > shale> slag > control Regression analysis between soil properties and adsorption maximum according to
the Frendlich equation were weakly positive correlated as follow: Clay % (r=0.6616) > silt +clay % (r=0.6496) > C.E.C (r=0.5825) > pH (r=0.5374) > Cac03 % (r=0.5284) > O.M % (r =0.4835) > silt (r = 0.4268) .
Also Langmuir equation in was positively correlated in the order: Clay % (r=0.8849) > silt + clay % (r=0.7291) > C.E.C (r= 0.7288) > pH (r = 0.6730) > silt % (r= 0.5367) > O.M (r= 5278) > CaC03 % (r= 0.2514) under different investigated soils. Key words: Shale, Slag, compost, Zinc, adsorption value.
