“…The existing of diazinon compounds effected to ecosystem of Lake Singkarak, according to [22] when Diazinon pesticide waste enter into the waters, will result the decreasing the water quality including physics (temperature and brightness), chemistry (pH, carbon dioxide, and dissolved oxygen), and biology (fish, plankton, macrophytes, and benthos), Furthermore make an imbalance in the aquatic environment. According to [23], the diazinon insecticide has a lower environmental persistence than organochlorines but has a higher level of toxicity. Diazinon is an organophosphate insecticide that acts as a competitive inhibitor of the activity of the acetyl cholinesterase enzyme that accumulates in the central nervous system and peripheral nervous system of fish [6].…”

Organophosphate pesticide is a pesticide derivate that is used widely by farmers because it has a high killing power against insects and easily disappears from plants. Organophosphate pesticide residues can accumulate in the environment and also cause acute and chronic poisoning in humans. Singkarak Lake in West Sumatra Province is surrounded by many agricultural and farming areas. One of fisheries resources that can be affected by activities at those areas is Bilih fish (Mystacoleucus padangensis). The study aims to determine the levels of organophosphate pesticide residues in Singkarak Lake’s water and Bilih fish. Seven organophosphate pesticide compounds: Diazinon, Fenitrothion, Methidathion, Malathion, Chlorpyrifos, Parathion, and Profenofos were analyzed. In June 2021, surface water and Bilih fish samples were collected from 10 sampling locations in Singkarak Lake. The organophosphate pesticide in the samples was determined using gas chromatography. The results showed that residues were detected in water samples of four locations (Ombilin, Tikalak, Sumani, and Paninggahan), but not in the other six locations (Batu Taba, Sumpur, Guguak Malalo, Saniang Baka, Muaro Pingai, and Tanjung Mutuih) as well as below 1 ppb. Methidathion, Malathion, Chlorpyrifos, and Parathion were detected in lake water at range 2 to 8 ppb. Except for the Bilih fish sample from Ombilin, the majority of the samples contained organophosphate residues. Diazinon, Fenitrothion, Methidathion, Chlorpyrifos, Parathion, and Profenofos were the organophosphate derivate found in the fish samples. Malathion compound was not found. The organophosphate residue concentration in Bilih fish ranged from 2 to 70 ppb.

“…The rapid increase in the adsorption percentage in the early stages is due to the metal ions occupying a considerable fraction of the surface reactive sites. Over longer periods, the metal ions become less easily accessible to empty active sites on the adsorbent surface and once the process has attained equilibrium, these sites become completely saturated [31]. The adsorption attains a constant rate after 30 min.…”

In this study, the sol-gel auto-combustion method is employed to synthesize barium hexaferrite (BaFe12O19) using carboxymethyl cellulose as chelating agent. The properties and identity of the synthesized BaFe12O19 nanoparticles were verified with X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), energy dispersive spectroscopy (EDS) and vibrating sample magnetometry (VSM). The adsorption efficiency of the prepared nanoparticles toward lead(II) metal ions was estimated using atomic absorption spectroscopy (AAS). The synthesized BaFe12O19 was utilized as an adsorbent for removing lead(II) from the aqueous solution. The utilization enhancement studies of the synthesized nanoparticles were influenced by several factors, which include incubation time, pH of metal ion solutions, adsorbent doses, initial lead(II) metal ion concentration and temperature. Under optimum conditions, when 0.20 g of adsorbent was used with 5 mg/L of lead(II) ion solution at a pH 6, the adsorption percentage was found to be 91.53%. Endothermic adsorption and the Langmuir isotherm models were found to best fit the data of lead(II) adsorption. Notably, the maximum adsorption capacity (qm) for lead adsorption was 4.57 mg/g. These findings demonstrated that the novel single material BaFe12O19 magnetic nanoparticles can function as a highly effective nanosorbent for the treatment of wastewater and they can effectively remove lead(II) ions.

“…The presence of these metals needs to be minimized or even removed, one of which is the adsorption method. The adsorption process using the suitable adsorbent is simple, effective in removing heavy metals from liquid waste (Yuan et al, 2020), and does not provide side effects of toxic gases (Azis et al, 2019).…”

Heavy metal concentration exceeding the threshold amount is hazardous to the environment, so it needs some treatment. The study aimed to know the capacity and kinetics of adsorption. This study used the adsorption method to remove the heavy metal ion Ni(II) using persimmon tannin gel. Influences of time contact, pH, and ion concentration in the adsorption process were also investigated. Results showed optimum adsorption at 60 minutes of time contact and pH 5. Variation of concentration made the adsorption decrease as metal ion Ni(II) concentration increased. The maximum adsorption capacity was 23.14 mg/g by using pseudo-second-order adsorption kinetic model.
