摘要
The oscillating behavior of thirteen amino acids [leucine (Leu), threonine (Thr), arginine (Arg), lysine (Lys), histidine (His), alanine (Ala), glutamine (Glu), glycine (Gly), methionine (Met), cystine (Cys), tryptophan (Trp), serine (Ser) and tyrosine (Tyr)] in amino acid- BrO?3 -Mn2+- H2SO4-acetone system is studied by using a potentiometric determination. With the help of the oscillatory induction period and oscillation period obtained by the oscillating wave, and Arrhenius equation, the kinetic parameters [the appar- ent activation energy (E) and pre-exponential constant (A)] and rate constant (k) of the above-mentioned oscillating re- action are estimated.
The oscillating behavior of thirteen amino adds [leucine (Leu), threonine(Thr), arginine (Arg), lysine (Lys), histidine (His), alanine (Ala), glutamine (Glu), glydne (Gly),methionine (Met), cystine (Cys), tryptophan (Trp), serine (Set) and tyrosine (Tyr)] in amino acid-BrOJ -Mn^(2+)-H_2SO_4-acetone system is studied by using a potentiometric determination. With thehelp of the oscillatory induction period and oscillation period obtained by the oscillating wave,and Arrhenius equation, the kinetic parameters [the apparent activation energy (E) andpre-exponential constant (A)] and rate constant (k) of the above-mentioned oscillating reaction areestimated.
