Utilization of ZSM-5/TiO₂ Powder and Membrane to Reduce Concentration Cu(II) and Cr(VI) Ions in Water

Abstract

Cancer is an effect caused by excessive concentrations of Cu(II) and Cr(VI) metal ions in the body. Including health effects of heavy metal ion poisoning industries arise when humans consume fish from various wastes, dyes, electroplating, paint, and battery. Techniques and processes have been developed to separate heavy metal ions which were very dangerous from water by ion exchange, chemical precipitation, and adsorption. Adsorption has no harmful side effects to health, simple, economical and easy to do. Natural materials can be used as adsorbents including ZSM-5, ZSM-5/TiO2 powder, and membrane. The purpose of this study is to determine the initial, final concentration and the percentage decrease concentration of Cu(II) and Cr(VI) ions in water by ZSM-5/TiO2 powder and membrane with variations gauze type and irradiation time. The results showed that the highest percentage reduction Cu(II) ion and Cr(VI) ion with 0.25% w/v ZSM-5/TiO2 powder during UV irradiation 75 minutes were 74.99% and 16.99%. The highest percentage reduction in Cu (II) and Cr (VI) concentration after passing through the ZSM-5/TiO2 membrane with gauze support 304-400 during 90 minute UV irradiation were 57.72% and 54.65%. As the conclusion ability of ZSM-5/TiO2 powder is greater than the ZSM-5/TiO2 membrane in reducing the concentration of Cu(II) and Cr(VI).

Decreasing of Mangan (II) in The Water Using Membrane of Moringa Seed Powder-TiO2 with Variation of Mass TiO2

“…Therefore, it is to decrease the concentration of Mn (II) in water with metal degradation methods that can be biological, chemical, and physical. The adsorption process uses ZSM-5 [6] , ZSM-5 membrane [7] , ZSM-5/TiO2 powder [8][9] [10] , and ZSM-5/TiO2 membrane [11] . The price of the material to make ZSM-5 powder is relatively high, it is necessary to substitute ZSM-5 from natural adsorbents such as Moringa oleifera seeds [8][9] , activated charcoal Moringa seed powder [14] , teak sawdust [15] , TiO2 photocatalyst process with gauze buffer media [16] , and membranes MSP/TiO2 [17] , and Polyvinylidene fluoride (PVDF) Blending TiO2-MSP membrane [18] .…”

“…The number of •OH radicals from the photocatalyst TiO2 and H2O causes the number of electrons to be accepted by the Mn (II) ion so that the Mn (II) content in the water decreases [19] . MSP/TiO2 membrane with 20 g MSP and variation mass of TiO2 1, 3, 5, 7, and 9 g [11] .…”

Determination of parameters affecting kinetic and thermodynamic values for lead removal Using wastewater treatment plant sewage sludge ash

“…Many different methods are used in the treatment of wastewater containing lead and other heavy metals. Chemical precipitation [18], adsorption [19][20][21][22][23], ion exchange [24,25], reverse osmosis [26] and membrane filtration [27] are the most widely used heavy metal removal methods. However, the adsorption method has been seen as a much more advantageous technique for wastewater containing low concentrations of pollution [28].…”
