Transient and steady-state photolysis of p-nitroaniline in aqueous solution

Study on the mechanism of photo-degradation of p-nitrophenol exposed to 254nm UV light

“…However, radicals generating as primary products after UV excitation and the sequential reactions have barely been focused on yet. As a direct way to study the primary species generating after the excitation of UV light, LFP has been recommended to be an effective method to study the mechanism of photochemical degradation [3]. In this article, LFP experiments have been employed to essentially elucidate the radical reaction mechanisms.…”

Electrooxidation and Kinetic Study of p-Nitroaniline in Acidic Solution

“…p-NA, due to having specific effect of an electron withdrawing nitro group at para position to an electron-donating amino group, has attracted much scientific attention [9]. p-NA has been detected by many techniques and methods such as spectro photometry, chromatography, Fenton oxidation process [5], surface-enhanced Raman scattering [10], flow electrochemical determination [11][12], transient photolysis, steady-state photo degradation [13] and electrochemical techniques. But electrochemical technique is the most proficient technique since it provides a very consistent outcome, simple to operate, highly sensitive, accurate, rapidly analyzed [14].…”

Behaviour of RO90 membrane on the removal of 4-nitrophenol and 4-nitroaniline by low pressure reverse osmosis

“…Different techniques have been used for the removal of 4NP and 4NA from aqueous solutions. Among chemical methods highlights Fenton [4] and photo-Fenton oxidation [6,7], reduction [8,9] and photolysis treatments [10,11] with the main drawbacks of the high energy consuming and high costs. Degradation with bacteria presents the problem of keeping the activity of the organisms [12,13].…”
