Development of new multifunctional filter based nonwovens for organics pollutants reduction and detoxification: High catalytic and antibacterial activities

Dopamine Grafted Iron-Loaded Waste Silk for Fenton-Like Removal of Toxic Water Pollutants

“…Plots summarized in Table 2 show that dye degradation exhibited good linear relationships of ln(C/C 0 ) versus reaction time up to a certain time where maximum number of dyes was degraded following pseudo-first-order kinetics. These results are consistent with those found in previous reports [10,24,33,[39][40][41][42].…”

“…The concentration of dyes is a precarious parameter of color removal rate, which influences the effectiveness of the removal process. The effect of dye concentration on the removal of dyes were studied in terms of different concentration (10,20,40,60, and 80 mg/L) of dye solutions. Results presented in Figure 8 show a certain influence on the removal rate of all three dyes due to the variation in concentration of the dye solution.…”

“…Many approaches have been introduced by the several researchers where hazardous aromatic dyes were removed by various processes like biodegradation, chemical oxidation, adsorption, and so on [4][5][6][7][8]. Various heterogeneous catalytic systems with metal oxides or hydroxides like CuO, ZnO, TiO 2, and FeOOH as catalysts, [5,[9][10][11] as well as advanced oxidation systems have also been introduced all over the decades [12][13][14].…”

Modification of fibrous membrane for organic and pathogenic contaminants removal: from design to application

“…Therefore, we studied the detoxication of water aer the removal process in terms of chemical oxygen demand (COD) analysis. Typically, the chemical oxygen demand of treated and untreated water studied as per "ASTM D1252-06-chemical oxygen demand (dichromate oxygen demand) of water" test method B using COD vials provided by CHEMetrics, Inc. (USA) where the nal COD was calculated using eqn (2) as similar to the method reported earlier 18,40 COD…”

“…Heterogeneous Fenton reaction using solid immobilized iron (zerovalent iron nanoparticles) has gained attention for degradation of various types of complex pollutants providing the prospects of reducing the consumption of iron and reusability of iron as well as functioning reactor in a commercially operable reaction condition. Our previous studies reported the effectiveness of zerovalent iron nanoparticles towards detoxication of water containing aromatic dyes, 12,18,19 phenolic compounds, 20,21 and bacteria strains. 18 However, considerable improvement is still necessary due to unsatisfactory activity in terms of leaching and easy oxidation of iron nanoparticles as well as in using fatal reducing agents (sodium borohydride) and discount in total detoxication of the pollutants.…”
