| Abstract: | The adsorption of Cu 2 and Pb 2 on algin is examined. The influence of temperature, pH and time on this adsorption are discussed. Freundilich isotherm is appropriate type for this adsorption, but constant n of Freundlich isotherm equation changes greatly at a higher temperature. Adsorption is a heat releasing process, and the adsorption rate increases with pH value and achieves more than 90% within 10 min.Key words chitosan, adsorption, heavy metal ionlated efficiently by using the statistical characteristics of the chaotic sequence. The mathematical formulas of BER are given and verified by simulation results theoretically and empirically. The relationship of the chip of chaotic sequence, noise and performance of this scheme is discussed. |
