Abstract：Thecontentofchromiuminsoilisdetectedeficientlybyflameatomicabsorptionspectrophotometryandthe theoretical adsorption effciencyofactivated carbonand nano cellose under diffrentconditionsand the actual adsorption effctin soil samples ofagricultural landand industrialland in thethe Pearl River Delta are studied.Theresearch results indicate thatactivatedcarbon exhibitsgoodsustainedremovalabilityinhighchromiumcontaminatedsoil，while nanocellose is suitable forrapid treatmentof lowchromiumcontaminated soil.Taking into account the soil chromium content and adsorbent cost，a reasonable adsorbentcan be selected forthe treatmentof chromium contaminated soil. The application of flame atomic absorption spectrophotometry and adsorption method not only improves the eficiency of chromium removal，but also provides new ideas for treating soil heavy metal polutionand improving soil environment.
