In this research, NiAl-LDH was synthesized using the coprecipitation method and modified with biochar and graphite to produce NiAlbiochar and NiAl-graphite composite materials. The adsorbent that has been synthesized is used for the application of adsorption of Fe(II) ions in aqueous solution. The resulting material was characterized by XRD (X-ray Diffraction) analysis, spectrophotometer FT-IR, BET analysis for determine the specific surface area and TG-DTA analysis. XRD diffractogram showed that the NiAl-Biochar and NiAl-graphite composite material had the diffraction pattern characteristic of the precursor. LDH that has been modified will have a larger surface area than the precursor. The surface area of NiAl-biochar reaches 438.942 m2/g and the surface area of NiAl-graphitereaches 21.595 m2/g. This composite material supports adsorbents with a large adsorption capacity to adsorb metals. Adsorption of Fe (II) using NiAl-Biochar and NiAl-graphite was stable for five regeneration cycles (<75.30%). The Fe(II) ion adsorption process tends to follow the Langmuir isotherm model which has a maximum capacity value (Qmax) of NiAl-Biochar composite material reaching 20 times with a value of 243.902 mg/g and the NiAl-graphite composite reaching 72.464 mg/g, so that the carbon-based composite material is considered effective. adsorbent to remove Fe(II) ion and can increase the stability of the structure for adsorption regeneration. The results of the analysis of thermodynamic parameters showed that the adsorption process was endothermic, tookplace spontaneously and the solid-liquid phase interface increased according to the increasing degree of disorder.

This research converts agricultural waste Longan (Dimocarpus longan) Peel is used in the adsorption process to reduce cationic dyes rhodamine-B and malachite green contaminants from aqueous solution. Longan (Dimocarpus longan) Peel was characterized by FT-IR, analysis XRD, SEM, BET, and TG-DTA. The characterization results show that Longan (Dimocarpus longan) Peel contains cellulose compounds and has a specific surface area 17.175 m2/g, with this Longan (Dimocarpus longan) Peel has the potential as a bio adsorbent. The adsorption capacity is proven by adsorption capacity (Qm) shows that the bioadsorbent adsorption of malachite green has a large adsorption capacity of 182.64 mg/g, while the adsorption capacity of rhodamine-B (Qm) reaches 52.557 mg/g and this bioadsorbent longan (Dimocarpus longan) peel is effective the adsorption was stable until the third cycle.
