The latest applications of chemodynamic therapy (CDT) combined with multifunctional nanomaterials in tumor treatment are summarized. Nanomaterials different characteristics can optimize the Fenton reaction and Fenton-like to make CDT produce distinctive enhancement effects. combination nanomaterials, various other therapies would promote multi-functionalization system, thereby enhancing antican...

The intensive production of fossil fuels has led to serious polycyclic aromatic hydrocarbon (PAH) contamination in water and soil environments (as PAHs are typical types emerging contaminants). Bio-Fenton, an alternative Fenton oxidation, which generates hydrogen peroxide at a nearly neutral pH condition, could ideally work as pretreatment recalcitrant organics, be combined with the subsequent ...

the heterogeneous photo-fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. the photocatalyst has been prepared by coprecipitation method. the rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. it has been observed thatphotocatalytic degradation follows pseudo first order kinetics. the effect of various param...

background: high amount of heavy metals in sludge is one of the major obstacles to its use on farms. the present study aimed to investigate the possibility of leaching heavy metals from wastewater sludge by fenton method and determine the optimum level of parameters, such as iron, hydrogen peroxide, time, and ph for fenton reaction.   methods: the effects of various parameters, such as ph (2-9)...

this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...

background textile dyes are the largest organic compounds associated with some problems for the environment. advanced oxidation process is the most effective method for dye removal from wastewater. objectives the aim of this study was to investigate the efficiency of the photo fenton process for decolorization of direct red 81 (dr 81) dye, and to determine the optimal process conditions. method...

This study evaluated the COD removal performances of classical-Fenton and photo-Fenton Processes by different prediction models. To optimize both Fenton processes performed in batch reactors, effects H2O2 dose, Fe(II) H2O2/Fe(II) rate, contact time were determined as independent variables Besides response surface methodology, three neural networks used to more reliably effectively predict behav...
