“…Dalam konteks abu batubara, oksida logam berat seperti Pb dan Cr dapat memiliki kelarutan yang rendah dalam air karena mereka cenderung membentuk senyawa kompleks atau endapan yang kurang larut (Rengga et al, 2019). Selama proses leaching, abu batubara berinteraksi dengan air, reaksi kimia dapat terjadi antara oksida logam dan air, membentuk senyawa yang mungkin memiliki kelarutan yang rendah.…”

Coal ash, stemming from the combustion process in power plants, emerges as a potential pollution source due to its metal content. Recognized for housing various metals with environmental contamination potential, this study meticulously delves into the metal analysis of chromium (Cr) and lead (Pb) within four distinct samples of fly ash (FA) and bottom ash (BA) sourced from diverse coal-fired power plants across Indonesia. Employing the batch leaching method, the coal ash samples (FABA) underwent a 6-hour immersion in deionized water, replicating environmental scenarios akin to rainwater interaction with coal ash at disposal sites. XRF analysis scrutinized the chemical composition of each sample, while the leaching filtrate underwent analysis via pH meter and AAS to ascertain pH values and the concentrations of Pb and Cr. Results unveiled a substantial pH variation in the leachate, fluctuating from the initial deionized water pH of 7.00 to a range between 6.86 and 9.18. Notably, subsequent leaching indicated undetectable concentrations of Pb in all samples, with most exhibiting low Cr concentrations post-leaching, except for FA-2, FA-4, and BA-4, which displayed modest Cr concentrations. The scarcity or low concentrations of Pb and Cr post-leaching suggest an efficacious process inhibiting heavy metal release. This study offers profound insights into the chemical intricacies of coal ash, underlining its potential environmental ramifications. The absence of detectable heavy metal concentrations post-leaching underscores a minimal risk of environmental pollution, underscoring the imperative to comprehend the chemical reactions intrinsic to the leaching process for optimal waste management strategies.

“…In the treatment of hazardous contaminants such as mercury(II) ions in polluted air, various types of adsorbents can be used (Sarah et al, 2021). Various methods have been applied such as adsorption, membrane technology, sedimentation, electrochemical technology, oxidation, reduction, coagulation, and flocculation in wastewater treatment containing heavy metals (Rengga et al, 2019). Adsorption is thought to be the most efficient and appropriate method due to its large absorption capacity, high efficiency, and low-cost materials, given mercury's high volatility and low solubility in water.…”

Mercury is harmful to humans and the ecological environment. The adsorption process is known as an effective method for removing heavy metals. This research is devoted to developing new adsorbents based on carbon materials to remove metal ions Hg(II) with carbon-based monolith adsorbents without and with manganese oxide fillers (KM and KMM). The results of adsorption efficiency, adsorption kinetics, and isotherm models were made in a batch system with varying concentrations of mercury solution from 2 mg/L to 6 mg/L with adsorbents without and with manganese oxide fillers (KM and KMM). The highest removal efficiency reached 96% on KMM and 47% on KM. The adsorption isotherm of Hg(II) ions corresponds to the Freundlich model, with intensity and volume constants obtained respectively 0.042 and 1.347 L/mg on KM adsorbents, while on KMM adsorbents the intensity and volume constants obtained are 0.291 and 2.079, respectively. L/mg. These results indicate that physical adsorption occurs more dominantly than chemical adsorption. The adsorption of Hg(II) ions was in accordance with the pseudo-first-order adsorption kinetics, with the adsorption capacity and rate constant on the KM adsorbent obtained were 0.0505 mg/g and 0.0072 g/mg, while the adsorption capacity and rate constant for the KMM adsorbent were on KM adsorbents obtained were 0.0848 mg/g and 0.0239 g/mg.

The presence of heavy metals is quite a serious problem, considering that their numbers continue to increase. Efforts to handle it have been carried out using various methods. An effective and cheap method is the biosorption method. This research to determine the absorption capacity of langsat peel (Lansium domesticum) for the absorption of Pb2+ metal ions using a column method. The parameters studied to determine optimum conditions were biosorbent particle sizes with size variations of 106, 150, 250 and 425 μm and flow rates of 1.2, 3.4 mL/minute. The results showed that the biosorption of Pb2+ metal ions was influenced by the biosorbent particle size and flow rate. The optimum particle size of the biosorbent is 106 μm and a flow rate of 1 mL/minute, with an absorption capacity of 14.615 mg/g and 14.345 mg/g, respectively.
