Abstract:This paper studies the characteristics of the distribution,transportation,and transformation of heavy emtals in the bed load,suspended load and water body of the Juma River.An adsorption and desorption model of suspended load for heavy metals is developed on the basis of experiments.The adsorption isotherm of heavy metals all obeys the Freundlich equation;and according to the mathematical model the values of K 1 and K 2 can be calculated.The effect of temperature,initial concentration and adsorbent concentration on the value of K 1 and K 2 is discussed and an empirical formula of K value is established. A comparison with the experimental value shows that the calculated result is satisfactory.
Keywords:Juma River  heavy metals  adsorption  desorption
