In the present work, degradation of p-nitrophenol (PNP) and its mineralization by a UV/Vis-based persulphate activation process was investigated. Firstly, screening processes as direct photolysis, alone activated radiation performed. The incidence demonstrated to have an important role in oxidant activation, allowing achieve highest PNP total organic carbon (TOC) removals. maximum oxidation (10...

the present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a bet surface area of 672 m²/g. the batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated carbon was 120min. the adsorption data was modeled by equilibrium and kinetic models. the pseudo...

Single-walled carbon nanohorn (SWCNH) was developed as new adsorbent for solid-phase extraction using 4-nitrophenol as representative. The unique exoteric structures and high surface area of SWCNH allow extracting a large amount of 4-nitrophenol over a short time. Highly sensitive determination of 4-nitrophenol was achieved by linear sweep voltammetry after only 120s extraction. The calibration...
