“…Unfortunately, the benefits of rambutan fruit are only known from the fruit's flesh, leaving the peels and seeds to be discarded. However, rambutan seeds and peels can be used again, specifically as an adsorbent (Rinaldi et al, 2018), (Purwiandono & Haidar, 2022), (Almuchty et al, 2020), (Winata et al, 2020), (Selvanathan et al, 2017), (Selvanathan et al, 2017), (Hasanah et al, 2022), (Lee & Ong, 2017), (Alrozi et al, 2012), (Krishnaiah et al, 2014). It turns out that rambutan, like coconut fruit, has a thousand benefits; aside from the peels and seeds, which may be reprocessed, other components of rambutan, such as leaves and stems, can also be reprocessed.…”

“…Another idea states that an acidic environment will cause an abundance of H + ions in the solution to compete with dye cations for adsorption sites, potentially reducing methylene blue adsorption. However, the adsorption of methylene blue appears to increase when the pH is greater than pH > 6 (Baek et al, 2010) (Alrozi et al, 2012). The adsorption of the dye pollutant, which is determined by the cation or anion categorization of the related pollution, determines the pH of the solution (Afroze & Sen, 2018).…”

Pollution of environmental streams and ecosystems is rising. One of the sources of water contamination is the wastewater from the textile, plastics, and mining sectors, which contains both organic and inorganic pollutants. Heavy metals and dyes in wastewater must be treated before disposal to protect the aquatic environment and human health. Due to its effectiveness, low cost, and simplicity of use, biosorption has emerged as a wastewater treatment option. Rambutan waste, in particular, is promising for commercial usage due to its extensive availability and efficiency. In this article, we review the usage of natural rambutan peels, seeds, leaves, and stems for the biosorption of water contaminants. We discuss the factors that influence pollutant removal. A pH of 6 to 12 is advantageous for cationic pollutant removal, whereas a pH of less than 5 is appropriate for anionic pollutant removal. More significant concentrations of pollutants generally result in lesser removal, whereas higher doses of biosorbent result in higher removal. The ideal adsorption contact time for rambutan peels and seeds was less than an hour. We also discuss the isotherms of the adsorption process.

The potential of using Empty Fruit Bunch (EFB), an agrowaste material, as a low-cost biosorbent for the removal of Reactive Black 5 (RB5) from aqueous solution was investigated in this study. The influences of solution pH, contact time, initial concentration and biosorbent dosage were studied in batch experiments at room temperature. Adsorption equilibrium was achieved after 30 min of agitation. The maximum adsorption uptake of RB5 dye occurred at pH 2, resulting in a rapid adsorption (more than 50% RB5 uptake) for the first 5 min of contact. Lower solution pH values showed better adsorption because the dye molecules tend to adsorb on positively charged adsorbent sites. Furthermore, higher biosorbent dosages increased the dye uptake by up to 90% due to the availability of more active adsorption sites. Both the pseudo-second-order kinetic model and the Langmuir model indicated that monolayer coverage on the adsorbent was dominant and that chemisorption was the rate-determining step.
