Phenol gives a toxic response in the natural water and leads to show harsh effects on human being, plants, and animals. At low concentration, the phenol gives a pungent taste as well as odour to the consumption of water. It is because of such reason that phenol is contained in the environmental legislation, and it needs to be analysed for providing better results. Therefore it should be eliminated before discharging or reusing the waste flow to the environment. The current review is mainly focused on the growth related to the detection of phenol in the water. In the review the state, advantages, disadvantages of different techniques are discussed in brief. The methods mainly involve the electrodes which hold the interest for using new material in the form of binders and also to advance the other types of electrodes. It is observed that for the electrochemist, the electrochemistry of electrodes is considered as the most commanding approach. The significant merits of using electrodes are an enhancement of the selectivity for the electroanalytical approach. The preparation methods for the electrodes are simple, secure, versatile, and most commonly, it has many controllable variables which enables it best material used in the starting of various applications. There are different aspects of applications such as industrial technology transfers purposes; it affects the electroanalytical chemistry and diverse other fields as well, namely energy conversion, catalysis, storage, etc. Copyright © VBRI Press.

The electrospun PVDF (Polyvinylidene Fluoride) nanofiber web is commonly agreed on a kind of new sensitive materials for the sensor testing the dynamic pressure and energy harvesting, and has the characteristics of fast response and high sensitivity of pressure. As a result of the nanofiber web, it must be packaged to collect piezoelectric charge and bear strong mechanical behavior before industrial practice. The packaging of PVDF nanofiber web is usually sandwiched by incorporating a pair of flexible electrode. However, the effects of the surface and mechanical properties of electrodes such as morphology, roughness and compressibility have not been well investigated yet. This work will introduce three common types of packaging electrode materials (adhesive copper foil tape, indium tin oxide (ITO) thin film, adhesive conductive cloth.) in previously published literatures, compares the piezoelectric output of their sensor prototypes under a periodic impact, and discusses the effect of surface morphology, electrical resistance, and compressibility. The results showed that it has higher output of PVDF piezoelectric sensor packaged by electrode materials with the smooth surface and low mechanical compressibility. This result provides a guideline for designing the textile electrode material for the PVDF nanofiber web.
