Abstract: Reactive X-3B red dye entering into environment is a typical persistent organic pollutant(POPs).Transport of the dye from water to soil and from soil to crop compartment is a continuous ecological process.According to the cognitionm,the quantitative depiction of the process using mathematical models was theoetically discussed.Some of the mathematical models were also verified using burozem-soybean,cinnamon soil-wheat,krasnozem-radish,aquorizem-rice systems.In particular,transference of the dye from water compartment to soil compartment by way of adsorbent mechanisms was accorded with the Langmuir model,and movement of the dye from soil compartment to crop compartment on the basis of root-absorbing mechanisms could be expressed using logarithmic crop-soil accumulation factor(CSAF) models.
