- -nitrophenol in aqueous solution below the World Health Organization’s drinking water equivalent level (DWEL) of 0.3 mg/L [49], 1 kg of 2Z-HYCA@650 °C will be required for ≈10 h 20 min and will treat 2.49 m3 of water per day. Removal of Escherichia coli Figure 10A shows that 0.5 g of 2Z-HYCA@650 °C essentially
- positive sites on the surface of the material. Even after 3 h of run time, the level of E. coli in the treated solution was still below the alert/action levels of 500 cfu/mL in drinking water for E. coli [52], as shown in Figure 10. This suggests the potential of the 2Z-HYCA@650 °C as a water disinfectant
- . The preparation is simple, and the resulting nanocomposite material is micro/mesoporous, unlike the initial hybrid clay material prepared in our previous study [1]. The new micro/mesoporous material is efficient for the removal of 4-nitrophenol and E. coli from drinking water. Zinc may not be
