Electrochemical Oxidization Of Herring Sperm Dna And Its Interaction With Histone, Juan Xu, Gui-Ping Huang, Hong Li, Wei Zhu
Journal of Electrochemistry
The voltammetric behavior of herring sperm DNA at glassy carbon electrode and its interaction with histone have been investigated by using cyclic voltammetry,differential pulse voltammetry,and fluorescence measurement.In the potential range of 0.20 V to 1.25 V,it is found that an irreversible oxidative peak is exhibited in acid solution,but in the neutral or alkaline solution two oxidative peaks are observed.Oxidative peak potential values show a negative shift with increasing pH via a slope of-57 mV·pH-1 and a linear relation with DNA concentration in the range of 0.45 to 8.20 mmol·L-1.In the presence of histone,the oxidative peak current of DNA and the …

Journal of Electrochemistry
The Ru-Ir /Ti electrode as cathode to electrolysis the synthetic phenolic wastewater was studied.The effect of the initial chloride concentration on the electrolytic treatment result has been discussed.Experiment result shows that the electrochemical oxidation of phenol suits to one kinetics equation in given electrolytic time.If the initial chloride concentration in wastewater increases,the time of the electrochemical oxidation of phenol can be shorten,in other words the apparent rate constant is greater.the middle matters of electrochemical oxidation of phenol in the chloride system detected out by HPLC and GC-MS is mainly 1-chloro-phenol,4-chloro-phenol,2,4-dichloro-phenol,2,6-dichloro-phenol,2,4,6-trichloro-phenol,all kinds of chlorohydrin,small aliphatic acid,and so on.The final production is …
