Abstract
In this analysis, the efficacy of adding coagulants such as Phaseolus lunatus and Phaseolus vulgaris (polymers) to the coagulation process during the treatment of arsenic aqueous solution to extract the arsenic metal was investigated. Experiments were carried out to evaluate the output of Phaseolus lunatus and Phaseolus vulgaris, both individually and in combination with arsenic, using the standard Jar test protocol. P.lunatus and P.vulgaris were given doses ranging from 1 to 3 gm. For P.lunatus and P.vulgaris, the (optimal) removal efficiency for total arsenic in the aqueous solution was obtained at 2gm. With chemical affinity between arsenic and coagulants used in this process, the valence state of arsenic may affect removal efficiency during the chemical coagulation process. pH is discovered to be a significant factor that has a direct or indirect impact on results. By overcoming the isoelectric point, the complex formed by the interaction of the inorganic pollutant and organic coagulant may aid in the removal of arsenic at pH 9 and 8. P.lunatus and P.vulgaris had optimised arsenic initial concentrations of 57.1µg/L and 42.6µg/L, respectively. The coagulation mechanism is more prevalent in water treatment, as shown by the above findings.
Highlights
Arsenic is found in water naturally in many parts of the world
This paper examines the use of enhanced coagulation to remove arsenic from groundwater, which represents a largescale arsenic problem
The effect of coagulant dose on arsenic eradication using Phaseolus lunatus and Phaseolus vulgaris was investigated separately using various coagulant dosages at a constant Arsenic concentration of 50μg/L, as shown in Figures 1 and 2, which confirmed that the percentage of arsenic removed increases as the coagulant dose is increased
Summary
Arsenic is found in water naturally in many parts of the world M.M, 1999; Smedley.P.L, and Kinniburgh.D.G, 2002).According to WHO guidelines, the arsenic level in water does not exceed 10μg/L for human consumption (World Health Organization, 1993). The leakage of arsenic from industrial effluents may be to blame for human health problems. Even though the exact amount of arsenic pollution in our Hyderabad research areas is unknown, there is no denying that this is a serious issue. Revised Manuscript received on July 05, 2021.
