Determination of hydroquinone in food and pharmaceutical samples using a voltammetric based sensor employing NiO nanoparticle and ionic liquids

A voltammetric sensor based on ionic liquid carbon paste electrode modified with NiO nanoparticle was used as a fast and high sensitive tool for determination of hydroquinone in real samples. The proposed sensor has a good ability for trace analysis of hydroquinone in the presence of other biological and pharmaceutical samples.101
