“…In recent years, there have been cases of cadmium poisoning that were brought on by drinking water that was polluted with Cd due to the corrosion of older water systems [4]. The Environmental Protection Agency (EPA) decided that 1 micrograms per liter of Cd were an acceptable amount for the country's drinking water [5]. On the other hand, the World Health Organization established a recommendation value for the amount of Cd that should be present in water at 0.5 micrograms per liter [6].…”

In this paper, vigna peel was used as a new way to get rid of Cd(II) from its aqueous solutions (VP). For this study, vigna peel (VP) was changed chemically with 25% by volume H2SO4 and ultrasonication at a frequency of 20 kHz to make a high-efficiency adsorbent. In this study, the material found was used to remove Cd(II) from the sample. The SEM and BET methods were used to figure out what the VP material was like. There were different amounts of Cd(II) (10–50 mg/L), pH (1–10), time (5–60 min), and VP dosages (50–1000 mg/50 ml). Maximum Cd(II) removal was found to be 98.6% at pH 5 with 50 mg/L of Cd(II) and 250 mg/50 ml of VP for 15 minutes. Pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetic models provided the best explanations for the equilibrium data.
