Owing to their remarkable selectivity, sensitivity, and rapid detection capabilities, optical sensors have garnered significant scholarly attention for the identification of various metal ions. Given its toxicological implications and pervasive application across numerous industrial processes, nickel(II) has become a focal point of research among metal ions. In recent years, a variety of optical chemical sensors exhibiting exceptional sensitivity and selectivity have been developed specifically for the detection of Ni(II). In the present study, a dimethylglyoxime(DMG) optical chemical sensor is employed to quantify trace amounts of Ni(II) using spectrophotometric techniques under controlled pH conditions. resulting in well-defined Ni(II) complex with characteristic absorption maxima at 568 nm. Optical sensing showed excellent linearity between absorbance and Ni(II) concentration, with correlation coefficients (R2) of 0.9952. and limits of detection (LOD) of 1×10-4. DMG has emerged as an effective effective reagent for the detection of Ni(II) ions in a range of aqueous samples functioning as an optical chemical sensor.
