Study On The Interaction Of Phenol, Aniline And Cu²⁺ In Soil

In the nature environment,there are so many pollutions from single source.But in fact pollutes many for associated and the comprehensive,Namely the many kinds of pollutant combined actions form compound pollution.Although the sole pollution has the reference significance,But appears as the formulation standard the data is insufficient,Therefore recent years our country massive developments to compound pollution research.That is why compound pollution becoming more popular recent years in our country.Comprehensive,select China's northeast common Dark-brown soil,Meadow-black Soil,Black soil as a test for soil,select phenol and aniline two representative organic pollutants,select the Cu²⁺ as a representative of heavy metal pollutants Research phenol,aniline and Cu²⁺ in soil correlation,regarding organic pollutant—The heavy metal compound pollution launches further studies.This study based on the test that soil adsorbtion effect for phenol,aniline and Cu²⁺ which on some different conditions about temperature,pH,ionic strength of different contact time.The result indicate that the equation of Henry,Freundlich and Langmuir-absorption can well show the soil adsorbtion effect for phenol and aniline.The process of adsorbtion that phenol and aniline in three soil style is spontaneous endothermic process.And the adsorbtion increase when concentration of phenol and aniline and the temperature increase,but the adsorbtion decline when the pH increase and ionic strength increase.The quantity of adsorbtion increase when the time increase and six hours basically reached equilibrium,with the ionic strength The larger decline over time increase the absorption of the increase, Adsorption of Elovich equation,Two-constant equation,a dynamics equation and the proliferation of parabolic equation.Three test for copper in the soil under the influence of phenol absorption of high-impact, for the performance of absorption was significantly decrease the absorption of aniline small impact.6 hours basically reached equilibrium.Adsorption of Elovich equation,Two-constant equation,a dynamics equation and the proliferation of parabolic equation.Henry,Freundlich and Langmuir-absorption equation can well show the hree soil absorption for Cu²⁺. The process of adsorbtion that three soil for Cu²⁺ is spontaneous endothermic process,And the adsorbtion increase when concentration of phenol and aniline,the temperature and pH increase,but the adsorbtion decline when the ionic strength increase.The quantity of adsorbtion increase when the time increase and twelve hours basically reached equilibrium.Adsorption accord with the Elovich equation,Two-constant equation,a dynamics equation and the proliferation of parabolic equation.The performance of three tested soil of phenol and aniline under the influence of copper ion adsorption is the absorption of copper increase when phenol presence,this phenomena is not obvious when aniline presence.The quantity of absorption increase when the pH value increase,but this phenomena is not obvious when phenol and aniline exists. Absorption capacity did not change significantly;adsorption capacity with the ionic strength larger drop, phenol and aniline on soil absorption of copper ions strength of the different impact of less visible, Performance in the low-intensity,impact absorption,high-strength,promote the absorption.With the increase in absorption time change,in 12 hours adsorption basic balance.Adsorption of Elovich equation, Two-constant equation,a dynamics equation and the proliferation of parabolic equation.
