In the modified fenton process steel scrap is replaced instead of FeSO4. Conclusion: Compared to the Fenton process, the modified Fenton process has more percentage of colour and COD removal within the limits of the study.doi:10.47059/REVISTAGEINTEC.V11I4.2185E. Krishnan...
A systematic approach was followed to optimise pH, temperature and the doses of FeSO4 and H2O2 for Feton's reagent (FR) to decolourize and detoxify the solutions containing of Remazol Red 120 (RR) dye and its mixture with Remazol Brillant Blue (RB) and Remazol Yellow 84 (RY) reactive ...
Results were expressed as mg FeSO4·7H2O per L of vinegar. Antioxidants 2018, 7, 139 4 of 17 2.6. Determination of Individual Phenolic Compounds by GC-MS Simple phenolic compounds were isolated from vinegar samples by solid phase extraction (SPE) on C8 Isolute columns, essentially as described...

FeSO4/H2O2 ratios found were not changed for both concentrations. The temperature affected the COD removal significantly at high degrees. Toxicity was completely removed for each concentration of RB5 at optimum removal conditions.Dipak R. Ahir
One, primary or zircon forming mineralisers, which promote zircon formation with good occlusion of hematite in the zircon matrix (NaF, NaCl, and BaF2 when using FeSO4 , Na2 SiF6 , and NaAl3 F6 with goethite), and two, secondary or modifying miner alisers, that have a collateral effect ...
With theaddition of Polyacrylamide (PAM), the reduction efficiencies of colour, COD and turbidity by FeSO4 -Al2(SO4)3 were 87%, 73.1% and 94.1% correspondingly. It was indicated that PAM significantlyreduced the turbidity of wastewater, however it virtually did not increase the efficiencies of ...
The use of mordants, especially CuSO4 and FeSO4, not only enhanced colour strength but also imparted different colours to the fabric. Compared to the unmordanted fabrics, colour fastness properties were mostly comparable or improved in the mordanted fabrics depending on the type and concentration ...
The optimal conditions for process were observed as; pH level 3.5, H2O2 concentration 1× 10-2M, FeSO4 concentration 3.5 × 10-5 mol L-1, temperature 50˚C and process time 50 min. The maximum 95% dye decolorization was achieved along with a significant (P 0.05) reduction of chemical ...
The influences of KAl(SO4)2, FeSO4, gallnut mordants or a commercial UV absorber on colour yield and fastness properties were further studied. Findings Optimum results were obtained when the fabric was dyed at 130掳C for 30 min in a dyebath containing 15 per cent (owf) annatto dye at pH...
