Imidacloprid is active compounds in Confidor 200 SL with  have toxical character. Degradation of Imidacloprid in Advanced Oxidation Processes (AOPs) method by using TiO2 catalyst can reduce toxic level. Advanced Oxidation Processes (AOPs) method which is used is Sonolysis, Photolysis, and Ozonolisis. The result of sonolysis, Photolysis, and Ozonolysis measured by spectrophotometer UV-Vis with λ 400-600 nm, and than optimum degradation waste after addition of catalys measured by HPLC. The result of degradation of Imidacloprid 6 mg/L using sonolysis without addition catalys is more smallest from addition catalys which degradated in 60 minute, temperature 25±1 °C. At the same time with Photolysis methode for addition catalys we get the degradation is more biggest from addition catalys. Degradation percentage of imidacloprid without addition of TiO2-anatase reach is small from with addition of TiO2. Measure using HPLC for each methode we get more than one peak in chromatogram. It means there are other coumpounds in imidacloprid solution.

Textile manufacturing is a multi-stage operation process that produces significant amounts of highly toxic wastewater. Given the size of the global textile market and its environmental impact, the development of effective, economical, and easy-to handle alternative treatment technologies for textile wastewater is of significant interest. Based on the analysis of peer-reviewed publications over the last two decades, this paper provides a comprehensive review of advanced oxidation processes (AOPs) on textile wastewater treatment, including their performances, mechanisms, advantages, disadvantages, influencing factors, and electrical energy per order (EEO) requirements. Fenton-based AOPs show the lowest median EEO value of 0.98 kWh m−3 order−1, followed by photochemical (3.20 kWh m−3 order−1), ozonation (3.34 kWh m−3 order−1), electrochemical (29.5 kWh m−3 order−1), photocatalysis (91 kWh m−3 order−1), and ultrasound (971.45 kWh m−3 order−1). The Fenton process can treat textile effluent at the lowest possible cost due to the minimal energy input and low reagent cost, while Ultrasound-based AOPs show the lowest electrical efficiency due to the high energy consumption. Further, to explore the applicability of these methods, available results from a full-scale implementation of the enhanced Fenton technology at a textile mill wastewater treatment plant (WWTP) are discussed. The WWTP operates at an estimated cost of CNY ¥1.62 m−3 (USD $0.23 m−3) with effluent meeting the China Grade I-A pollutant discharge standard for municipal WWTPs, indicating that the enhanced Fenton technology is efficient and cost-effective in industrial treatment for textile effluent.

Green Technique

Advanced oxidation processes (AOPs) are considered to be vital methods for treating the contaminations produced mainly by the human activations. In present-day, UV light or solar light, bulk and nano- photocatalysts are often used to enhance this technology by creating the highly reactive species such as the hydroxyl radicals. Extreme hydroxyl radical is considered as a key to start the photoreaction. Photoreaction is widely used in treatment of Lab and industrial contaminations, preparation of compounds and produced the renewable energy, so it’s classified as green technique. In order to improve the efficiency of this reaction with fabrication the surface of the used photocatalyst such as metal doped, sensitized and produced a composite as bulk catalyst or nano catalyst.

This work reports hydrotalcite and zinc-substituted hydrotalcite (MeAlLDHs) anionic clays as novel catalytic formulations for some environmental applications regarding specific industrial coloured effluents. In this context, layered double hydroxides, covered or with tailored compositions, were synthesized, characterized using advanced analytical analysis techniques (XRD, FTIR, SEM) and tested in specific environmental applications. More specifically, LDHs samples were tested as catalysts for different treatments of coloured effluents, especially some advanced oxidation processes (i.e.heterogeneous advanced oxidation processes with H2O2of Orange 16 dye-containing effluent). The influence of some operating factors such as catalyst type, concentration of hydrogen peroxide, presence of ferrous ions or UV light, contact time was studied, and the adequate operating values were established. Results show that Orange 16 removal is more than 70%, in specific operating conditions, for two of new tested materials (ZnAlLDH 3:1, and MgAlLDH 3:1). Moreover, the action of UV radiation was found efficient in decomposition of Orange 16 dye in the presence of all four tested catalytic materials, improving with more than 40-50% the color removal.

Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater treatment. The main reactions and the operating parameters (initial concentration of the target compounds, amount of oxidation agents and catalysts, nature of the wastewater etc) affecting these processes are reported, while several recent applications to wastewater treatment are presented. The advantages and drawbacks of these methods are highlighted, while some of the future challenges (decrease of operational cost, adoption of strategies for processes integration) are discussed.

Oxidation Efficiency

Nowadays, the attention of many researchers and scientists is focused on wastewater treatment technologies which are designed to remove toxic and/or persistant compounds. PAHs belong to this type of compounds. Studies have shown that advanced oxidation processes (AOP-advanced oxidation processes) can be used for PAHs degradation. One of the AOP methods is oxidation using Fenton's reagent (Fe2 + / H2O2). The aim of this modification is a search for alternative sources of hydroxyl radicals than H2O2 and support that processes by UV light.. The aim of the study was to determine the efficiency of photocatalysis of low molecular weight PAHs in pretreated coking wastewater under Fenton reaction conditions. The source of hydroxyl radicals was calcium peroxide and the process was supported by UV radiation. The oxidation efficiency was assessed on the basis of PAH analyzes in the pre-and post-oxidation samples. Qualitative and quantitative identification of PAHs was carried out using gas chromatography in combination with GC-MS mass spectrometry. The decrease in the concentration of the analyzed carbohydrates was in the range of 17 to 96%. Studies have shown that calcium peroxide can be an alternative source of hydroxyl radicals for the PAH degradation present in coke wastwater.
