limit are 8.25×10-8 mol·L-1 and 5.64×10-9 mol·L-1, corresponding regression coefficient are 0.9922(n=11) and 0.9955(n=12), respectively, and the possible mechanism was discussed.Chapter III: Determination of trace amounts of some metal ions by transient chaotic regime in the B-Z oscillating systemIn this part, a determination of trace amounts of some metal ions in the batch B-Z oscillating chemical reaction catalyzed by ferroin was made. The optimum conditions for the determination have been examined. The transient chaotic regime is quantified by the product of the largest Lyapunov exponent and induction period, which is linearly proportional to the negative logarithm of concentration of metal ions. A possible mechanism was also discussed.Chapter IV: Determination of Cu2+ and 1-naphthylamine using the perturbation of non-equilibrium stationary state in the B-Z oscillating chemical reactionA highly sensitive method is proposed for the determination of Cu2+ and 1-naphthylamine in the batch B-Z oscillating chemical reaction catalyzed by ferroin., And a non-linear chemical system far from thermodynamic equilibrium is also described. The method is based on the non-equilibrium stationary state close to a bifurcation point. The optimum conditions for the determination have been examined. The results show that the change in oscillating amplitude was linearly proportional to the negative logarithm of the concentration of Cu2+ and 1-naphthylamine from1.3×10-5 to 6.5×10-10 mol·L-1 and 7.5×10-5 to 1.5×10-6 mol·L-1 respectively.Meanwhile, the results obtained were compared with other determination methods.Key words: B-Z oscillating chemical reaction; regular oscillation; chaos; non-equilibrium stationary state; determination悁究生：魏晓霞IV专惄：分析化恘独创性声明本人声明所呈交的论文是我个人在导师指导下进行的研究工作 及取得的研究成果。尽我所知，除了文中特别加以标注和致谢的地方 外，论文中不包括其他人已经发表或撰写过的研究成果，也不包含为 获得西北师范大学或其他教育机构的学位或证书而使用过的材料。与 我一同工作的同志对本研究所做的任何贡献均已在论文中作了明确 的说明并表示了谢意。签名：日期： 关于论文使用授权的说明本人完全了解西北师范大学有关保留、使用学位论文的规定，即： 学校有权保留送交论文的复印
