Letters in Applied Nano Bio Science Platinum Open Access Journal (ISSN: 2284-6808), Volume 10, Issue 2, 2021, 2078 - 2084 https://doi.org/10.33263/LIANBS102.207820842284-6808http://ir.duan.edu.ua/handle/123456789/3893A modern and flexible spectrophotometric method for copper determination in food has been proposed to be posted on the electrochemical tracks. The theoretical analysis of the correspondent model confirms the efficiency of the electrochemical reaction for either electroanalytical or electro-synthetical or eliminative processes for copper. As for the oscillatory instability, it will be caused by either chemical or electrochemical influences on the double electric layerencopper ion; electrochemical sensor; complexation; 1(2-pyridilazo)-2-naphthol; stable steady-stateArticle
