“…One of the most common heavy metal wastes is Fe(II), often found in the textile, metallurgical, agrochemical, and mining industries (Altalhi et al, 2021). Fe(II) ions can be very dangerous if they accumulate excessively in the body and damage the liver (Harimu et al, 2020), kidneys and other organ systems. Fe(II) ion waste can cause turbidity and corrosion, which harms the environmental ecosystem (Song et al, 2017).…”

Synthesis of carbon dots from soybeans with urea doped (N-CDs) has been successfully conducted using the bottom-up approach via the hydrothermal method. The N-CDs showed a dark brown solution, indicating the carbon dots formed. This study analyzed the effect of optical properties before and after Fe (II) ions addition on the sensitivity of N-CDs. N-CDs characterizations were analyzed using UV-Vis Spectrophotometer and Photoluminescence Spectroscopy (PL). The results showed that the absorbance spectrum range is from 200 to 600 nm, with its absorbance peak at 290 nm. The band gap energy obtained is 3.32 eV, which indicates that N-CDs are semiconductors. The N-CDs solution resulted in good fluorescence when observed under ultraviolet light (395 nm) and emitted a bright green color. N-CDs' sensitivity when sensing Fe (II) ions with a minimum Limit of Detection (LOD) is as low as 5.7 nM. Thus, N-CDs can be used as biosensors with an easy and environmentally friendly method.

In general, well water or ground water often contains iron (Fe) and manganese (Mn) ions in it. One of the effective water treatment processes to remove heavy metals is adsorption. Natural adsorbents such as chitosan can be effective adsorbents used to reduce heavy metal concentrations in the environment. One of the weaknesses of chitosan is the strength of the mechanical structure and low stability. Therefore, crosslinking modifications were carried out to improve the mechanical structure and reduce solubility. This study aims to determine the effect of sodium tripolyphosphate on the process of making chitosan shrimp shell-sodium tripolyphosphate adsorbent and to determine the optimum conditions of the variation of the adsorbent and the mass used. The research variables used were the sodium-tripolyphosphate concentration of 0.25%; 0.50%; and 1.00%, the mass of the adsorbent in the column was 5 grams and 7.5 grams, and the sampling times were 20 minutes, 40 minutes, 60 minutes, 80 minutes, 100 minutes, 120 minutes, 140 minutes and 160 minutes. The results showed that the 1% chitosan-sodium tripolyphosphate adsorbent with a mass of 7.5 grams was the most optimal in reducing the content of Fe by 92% and Mn by 93%.

Growth and development in the industrial sector has made residents contribute to the waste that enters the environment. Imperfect waste treatment causes pollution to the environment and waters, so the water quality has decreased. The decline in water quality is caused by water pollution where foreign substances enter and leave. One of them is heavy metal. A number of studies have been carried out to treat and remove heavy metal ions in waters, one of which is the adsorption process. The adsorption method usually utilizes waste that is often disposed of and even modifications or activations are carried out in order to expand the surface area of the absorbent material. This review article discusses the adsorption method by utilizing Indonesian typical fruit peel waste for the last 10 years. From several studies collected, it was found that waste from typical Indonesian fruit peels was effective in absorbing heavy metal waste. Fruit peel waste that has high effectiveness is lemon peel waste with an absorption capacity of 98.4% on Cd metal, with an pH 8 and optimum contact time of 2 hours. This review can be an alternative for the manufacture of other absorbent materials and eliminate metal pollution in the aquatic environment.Keywords : Water pollution, Heavy Metals, Adsorption, Indonesian Fruit Peel Waste
