“…Heavy metals in the environment can be found in water, atmosphere and sediments (Rhaman et al, 2020). It has been reported that the concentration of heavy metals to be elevated in the wastewater generated by various anthropogenic causes, for instance stainless steel welding, construction, structure demolition, lead piping and fittings fertilizer production (Ebrahimi et al, 2019), pesticide production (Liu et al, 2019) and the intensification of agriculture output (Rhaman et al, 2020). Among the heavy metals on the earth, Iron (Fe) is the most common metal as it is essential nutrient for enzymes and proteins in humans, plants and algae (Zhang et al, 2014).…”

“…Recently, the high cost issue of carbon that restricts its application has been resolved by utilization of agro industrial and agricultural biomass wastes as biosorbents (BS). Various types of the biomass wastes have been used as BS of Fe ion from water including palm oil (Khosravihaftkhany et al, 2013) coffee and tea powder (Elsherif et al, 2018), carrot (Ebrahimi et al, 2019), olive stone (Corral-Bobadilla et al, 2021), rice husk ash (Hosseinzadeh & Mohammadi, 2016) and orange peel (Adebayo et al, 2016).…”

In recent years, various industrial activities have introduced a high concentration of iron in the waterbody which causes serious problem to environment. This paper proposed the application of Exhausted Coffee Husk (ECH) as the biosorbent (BS) for removing iron (Fe) (II) in the aqueous solution. The ECH was carbonized into biochar before performing biosorption of the heavy metal ion. The effect of carbonization temperature, time and rate on the performance of the ECH biochar for removing Fe (II) were evaluated. The percentage of removal efficiency (RE) and the capacity of biosorption (mg/g) were considered as the determining parameters. The pyrolysis temperature was varied in a range of 200-600 °C with 50 °C of interval, while the time was in between 1h – 3h with a n interval of 0.5 h, and the temperature gradient of 5 – 25°C/min. The results showed that the temperature had a significant effect on the properties of the ECH biochar as BS for Fe (II). The temperature of 550 °C, at 1.5 h of time and 25 °C/min was chosen as the suggested carbonization temperature of biochar from ECH for biosorption of Fe (II). Keywords: Agro-industrial solid waste, Biosorption, Carbonization, Exhausted coffee husk (ECH), Heavy metal.
