Abstract

Research on the efficiency of reverse-osmosis drinking water depot to decreased levels of iron (Fe3+), Copper (Cu2+) and Zinc (Zn2+) ions have been done. The raw, the treated, and waste water are filtered using reverse osmosis (RO) three times a week. HNO3 then was added to the sample until it reached 15 mL. The determination of the concentration of the three ions was performed using atomic absorption spectrophotometer (AAS). The results showed a decrease  of Fe3+ concentration of 73.21%, for Cu2+ decrease by 80.25%, while Zn2+ decrease by 82.08%. For waste water obtained iron ion concentration of 0.1794 mg/L, for Cu2+ by 0.0239 mg/L, while Zn2+ by 0.0962 mg/L.

Abstract

Water is an essential requirement for human existence. In addition to traditional water usage, water is essential for enhancing the quality of human existence and facilitating industrial and technological endeavors. An investigation was conducted on the contents of Cadmium (Cd), Copper (Cu), Iron (Fe), and Zinc (Zn) in drinking water from drilled wells in Surbakti Village, Karo District, employing Atomic Absorption Spectrophotometry (AAS) techniques. Sampling occurred during weeks 1, 2, 3, 4, and 5 and was subsequently digested with concentrated nitric acid until a volume of 15 mL was attained. The metal concentrations of Cd, Cu, Fe, and Zn were quantified using Atomic Absorption Spectroscopy (AAS) using a calibration curve. The findings indicated a concentration of Cd at 0.0031 mg/L, Cu at 0.0470 mg/L, Fe at 0.2741 mg/L, and Zn at 0.2929 mg/L. In this instance, Cd produced a greater concentration of drinking water standards compared to Cu, Fe, and Zn. Nonetheless, it nonetheless met the drinking quality standards established by Regulation Minister of Health No. 492/Menkes/Per/VII/2010.

Abstract

Heavy metals are often found in river water polluted by industrial processes. To separate heavy metals from river water, blood clam shells (Anadara granosa) are used as adsorbents. This study aims to analyze the determination of Belawan river water pollution based on the Aquatic Insect Diversity Index and analyze the content of heavy metal (Ni) in waste by utilizing blood clam shell waste as an adsorbent. The method used is solid phase extraction. Based on the diversity index data, the condition of the Belawan River waters in the Control area is not polluted (H' 2.18), Settlement Area 1 is lightly polluted (H' 1.94), Settlement Area 2 is lightly polluted (H' 1.70), Industrial Area 1 is moderately polluted (H' 1.47), and Industrial Area 2 is lightly polluted (H' 1.7). The percentage of heavy metal (Ni) absorption in Residential Area 1, Residential Area 2, Industrial Area 1, and Industrial Area 2 were respectively 28.57%, 33.33%, 31.11%, and 34.38%. This shows that blood cockles (Anadara granosa) are able to absorb Ni metal up to 34.38%. Ni levels < 0.05 mg/L so it can still be used (PP No. 22 of 2021).

Abstract

Research has been carried out on the adsorption of iron (Fe) and zinc (Zn) metal levels using activated zeolite with acid and base in healthy water. Characterization was carried out on activated zeolite using X-ray Fluorescence (XRF). Samples were taken from borehole water from Puji Mulyo area, Deli Serdang, and preserved with HNO3 until pH < 2, then digested. Determined the concentration of iron (Fe) and zinc (Zn) before and after the addition of activated zeolite by NaOH and HCl using an Atomic Absorption Spectrophotometer (AAS) with length-specific waves are 248.3 nm for iron (Fe) and 213.9 nm for zinc (Zn) metal. The results showed that the concentration of iron (Fe) and zinc (Zn) in the borehole water after the addition of activated zeolite decreased. Zeolite activated by NaOH absorbs iron (Fe) metal by 68.60% and absorbs zinc (Zn) metals by 37.91%. Meanwhile, Zeolite activated by HCl absorbs iron (Fe) by 42.37% and absorbs zinc (Zn) metal by 15.17%. This research shows that the effectiveness of percentage (%) decreasing the concentration of iron (Fe) and zinc (Zn) metal using activated zeolite with NaOH was more significant and more effective than activated zeolite with HCl.

Abstract

The wastewater from the metal coating industry comprises hazardous and poisonous metals, necessitating the reduction of its concentration before its release into water. The typically employed chemical technique involves the addition of Poly Aluminium Chloride (PAC), which causes the hazardous element to accumulate due to the subsequent application of Poly Aluminium Chloride (PAC). Next, the metal content is measured and determined using the atomic absorption spectrophotometry. This study employed the electrolysis technique utilizing carbon electrodes. The liquid waste undergoes electrolysis with voltage changes of 8, 11, 14, and 17 volts for 2 hours. The investigation yielded the optimal voltage for minimizing the metal content. The voltage applied to the metal is 17 volts. The reduction in the concentrations of Cr, Zn, and Cd metals achieved with the optimal voltage is 63.02%, 70.02%, and 80.14%, respectively.

Abstract

Activated carbon is a highly popular adsorbent for the absorption of metal ions. Lignocellulosic materials can be used to produce activated carbon, which is both renewable and abundant, as well as being cost-effective. The objective of this research is to investigate the reduction of iron (Fe) and sodium (Na) levels in the artesian well by utilizing activated carbon made from rubber shells. The materials utilized include rubber shells, a solution containing 10% H3PO4 (phosphoric acid), water from an artesian well, and distilled water (aquadest). The carbonization process was conducted at 300º C for 1 h, using an adsorbent size of 120 mesh. In addition, chemical activation was performed using a 10% H3PO4 solution for 24 h, followed by physical activation through heating in a furnace at a temperature of 500ºC for 1 hour. The acquired activated carbon is utilized for the absorption of Fe and Na. The activated carbon was characterized using X-ray diffraction (XRD), and the concentration of Fe and Na minerals was determined using an Atomic Adsorption Spectrophotometer (AAS). The results indicated a reduction of 97.9% in the concentration of iron (Fe) and a decrease of 90.01% in sodium (Na) levels.

Abstract

Through the use of commercial and cassava peel activated charcoal, research was done on how to lower the levels of iron (Fe) and copper (Cu) in well water that had been excavated. X-ray diffraction (XRD) was utilized to conduct the activated charcoal test. The samples were collected from the wells of individuals residing in Kelurahan Sumber Karya Binjai Timur. Water samples were treated with concentrated nitric acid (HNO3) and decomposed. The concentration of iron (Fe) and copper (Cu) was determined before and after adding activated charcoal made from cassava peel and commercially available activated charcoal, with masses of 1, 2, 3, 4, and 5 g. This was done using Atomic Absorption spectrophotometry (AAS) at specific wavelengths of 248.3 nm for Fe and 324.8 nm for Cu. The research findings indicate a decrease in iron (Fe) and copper (Cu) concentration before and after. The amount of activated charcoal made from cassava peel was varied from 1g to 5g. As the mass increased, the iron (Fe) concentration fell by 94.08%, 97.53%, 99.01%, 99.10%, and 99.07% respectively. The copper (Cu) content was reduced by 92.73%, 96.36%, 96.36%, 98.48%, and 97.12%. For commercial activated charcoal with varying masses of 1, 2, 3, 4, and 5 grams, the  concentration of iron (Fe) was reduced by 0.27%, 52.41%, 72.70%, 98.85%, and 98.09%, respectively. The copper (Cu) content reduced by 32.22%, 71.25%, 95.31%, 98.18%, and 96.06%.
