The aim of this study was to find out an available and low cost material to reach the permissible levels of the heavy metals Mn 2+ , Fe 2+ and pb 2+) in the contaminated water (ground and industrial waste water) taken from Kaha, El-Qulayoubia Governorate using multi walled carbon nanotubes (MWCNTs) prepared from chemical vapor deposition (CVD) and ferric oxide nanoparticle(Fe2O3) with potassium permanganate(KMnO4). Also, it involved the characterization of MWCNTs and Fe2O3 nanoparticle and determine the optimal conditions for the treatment. The effects of MWCNTs, Fe2O3 nanoparticle and KMnO4 on removal of manganese , iron and lead from contaminated water was the main target of this investigation. In this work the highest initial Mn 2+ , Fe 2+ and pb 2+ ion concentrations (C0) were found to be 3.42 , 4.2 and 23 mg/L, respectively, were treated with multiwall carbon nanotubes ,ferric oxide and potassium permanganate. MWCNTs was of 20-30 nm outer diameter, 5-10 nm internal diameter, surface area of 207.13 m 2 /g, carbon content 90.05%, oxygen content 6.9% and purity above 87%,while, Ferric oxide particle size averaged 5-10 nm, ferric content 44.64%, oxygen content 41.67% and carbon content 10.97%. The optimum conditions for removing Mn 2+ and Fe 2+ ion from the contaminated water with MWCNTs/KMnO4, were a pH of 7.5, volume KMnO4 0.25 mL, adsorbent weight of 0.05 g and a contact time of 90 min. The optimum conditions for removing Pb 2+ ion with Fe2O3/KMnO4 were a pH at 6.7, adsorbent weight 0.06 g, volume of KMnO4 1.25 mL and a contact time of 120 min.

“…To remove potassium permanganate from water before it is released as wastewater, several technologies and techniques such as biological degradation, ion exchange, membrane separation, oxidation by chemical agents, and sorption have been developed and implemented [11,13]. Sorption is one of the most widely utilized techniques due to its simplicity, high sorption capacity, environmental friendliness, nontoxicity, and availability of a large range of sorbents [11].…”

The powder of Ocimum Basilicum leaves was treated by zinc chloride (ZnCl2) and applied as a new and low-cost sorbent for extraction of permanganate anions (MnO4−) from liquid phase. The functional groups of the ring stretching vibration, –NH2 deformation, stretching of C-O, stretching of CH, and stretching of –NH were found in the sorbent of zinc chloride Ocimum basilicum leaves powder (ZCOBLP) at 1516.21, 1629.33, 1047.00, 2929.88, and 3294.93 cm−1, respectively. This adsorbent has 8.3 pHZPC, 117.27 m2·g−1 surface area, 0.00711 cc·g−1 pore volume and average pore diameter of 264.144 Å. The outcomes of sorption experiments designate the positive impact for temperature, time of agitation, and started concentration of MnO4− and negative impact for pH. The optimal conditions were 1300 mg·L−1 as started adsorbate concentration, 55°C as solution temperature, agitation time of 420 min, and pH of 1.5. The outcomes of the equilibrium and dynamic approve that this sorption is spontaneous and heat-absorbing process, and the obtained data were described well by isotherm model of Langmuir and 2nd-order dynamic model. The capacities of this sorption were 588.235, 625.000, 666.667, and 714.286 mg·g−1 at 25, 35, 45, and 55 (°C), respectively. The superior sorption capacities of the uncostly ZCOBLP will make it successfully used for MnO4− ions extraction from liquid phases.

“…Then the CCF/CF were separately added into the evaluation reactor shown in Figure 13. After that, the nitrobenzene compounds wastewater was poured into the unit, the test was operated in aerobic condition (50 L/min) and anaerobic condition, respectively [18]. The optimum operating conditions of CCF and CF were gathered from the test of TNCs, CODcr and BOD 5 , respectively.…”

Iron powder, Kaolin powder and CuSO4∙5H2O were employed as the main materials for the pilot-scale production of Fe/Cu catalytic- ceramic-filler (CCF) by way of wet type replacement-thermo-solidification. The physical properties, half-life, microstructure, removal rate of nitrobenzene compounds and the biodegradability-improvement of military chemical factory comprehensive wastewater were tested in comparison with commercial Fe/C ceramic-filler (CF). Catalytic micro-electrolysis bed reactors (CBRs) designed as pretreatment process and BAFs (Biological Aerated Filters) were utilized in a 90 days field pilot-scale test at last. The results showed the characteristics of optimum CCF were: 1150 kg/m3 of bulk density, 1700 kg/m3 of grain density, lower than 3.5% of shrinking ratio, 3.5% of 24 h water absorption, 6.0 Mpa of numerical tube pressure, 0.99 acid-resistance softening co-efficiency and 893.55 days of half-life. 25% addition of Fe with 1% of copper plating rate was efficient for the removal of nitrobenzene compounds and significant in promoting the biodegradability of military chemical factory comprehensive wastewater. The two-stage design of CBRs and BAFs showed high dependability and stability for the practical engineering application.
