“…The adsorption capacities of lemon peel adsorbent for dyes were found to be 50.3 and 34.5 mg/g for MO and CR, respectively. Batch adsorption studies were conducted to remove cutting oil from wastewater using activated lemon peels [64]. The effect of various important parameters, namely, pH, dose of adsorbent, contact time, mixing speed, and initial oil concentration, and their optimum conditions for maximum sorption efficiency were studied and results indicated that adsorbent dosage of 5 g/L, contact time of 70 min, mixing rate of 45-50 revolutions/min, and pH of 2 provided maximum oil removal efficiency in this study.…”

“…The dried lemon peels were soaked in a beaker containing 1000 ml of 0.5 M HNO 3 for about 30 minutes. This was done to neutralise the peels surface which could stop the NaOH reaction (Tembhurkar et al, 2012). Afterwards, the peels were rinsed with distilled water and extra pure water.…”

“…However, if oil is explored, transported, stored, and used too widely, chances of oil spillage are high hence, posing severe problem and damage to the environment. The oil spilled is not only messy but is also hazardous and will eventually threaten our lives (Tembhurkar et al, 2012).…”

While the discovery of oil contributes a lot towards a country’s economy and technological development, it is also the cause for oil pollution. As such, this study proposes to use lemon peel waste as a low-cost adsorbent to manage oil pollution. For the untreated adsorbent, the lemon peels were cut into small pieces and dried under sunlight for 48 hours. Then, it was further dried in an oven for 24 hours and ground into powder. For the treated adsorbent, the lemon peels were soaked in 0.5 M of sodium hydroxide (NaOH) solution. The adsorbent was used to adsorb different types of oil (diesel oil, lubricant oil, waste vegetable oil) and in different types of water (ocean water, lake water, tap water) with different amounts of adsorbent which is 0.2 g, 0.4 g, 0.6 g, 0.8 g, and 1.0 g for adsorbent dosage experiment. While for types of water experiment, a ratio for volume of water and oil of 3:1, and constant mass adsorbent was used. The result showed that untreated adsorbent can adsorb higher amount of oils than treated adsorbent. The oil that could be easily adsorbed using lemon peels adsorbent is diesel oil with 89.91% adsorption. For the types of water, the result changes according to different types of water and oil used. It was found that the higher the mass adsorbent, the lower the percentage of oil removal. The highest percentage of diesel oil removed in ocean water is 81.68%. While the removal of lubricant oil and waste vegetable oil in lake water is 66.6% and 72.13%, respectively. Scanning Electron Microscopy (SEM) shows that treated lemon peels had small pores compared to untreated lemon peel waste. This study demonstrated and proposed that the lemon peel waste has a good potential in low-cost oil waste removal.

“…Batch absorption studies were conducted to eliminate cutting oil from wastewater using stimulated lemon husks [55]. The effect of different important parameters, namely, pH, dose of adsorbent, contact time, mixing speed, and initial oil concentration, and their ideal stipulations for maximum sorption efficiency were examined and results indicated that adsorbent dosage of 5g/L, contact time of 70 min, mixing rate of 45-50revolutions/min, and pH of 2 provided maximum oil elimination efficiency in this study.…”

Towards the future of green, sustainable and renewable products the suggestion of using the agriculture biomass in the coming decades got increased. Biomass material is one of the important sources of alternative material for the production of biocomposite products. An increasing global awareness about environmental issues is acting as the driving force behind the utilization of biomass material as valuable products. Bio-waste materials (agricultural waste) have been recognized as an ecological burden for the society they stimulated new gateways for the production of renewable, low cost and sustainable adsorbents for water treatment applications. In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and bacteria. Adsorption has proved that it is the best process of water treatment technologies, because of its significant advantages. Different modification methods of waste-based adsorbents, have also been presented to highlight and discuss the key advancements on the preparation of novel adsorbents using agricultural "agro-waste". Adsorption mechanisms responsible for pollutants removal by waste-based adsorbents have also been discussed. It also focuses on the computational aspects of binding of biomolecules to nanoparticles (NPs) and some of the applications of the biosynthesized NPs as water purification. The nature acts like a large ''bio-laboratory" comprising of plants, algae, fungi, yeast, etc. which are composed of biomolecules. These naturally occurring biomolecules have been identified to play an active role in the formation of nanoparticles with distinct shapes and sizes thereby acting as a driving force for the designing of greener, safe and environmentally benign protocols for the synthesis of NPs. The biosynthesis of NPs using waste materials will help researchers not only to design safer nanomaterials but also to promote the understanding of health and safety considerations of NPs. Useful materials can be produced easily even at reasonable scale because the biomaterial based routes eliminate the need to use toxic chemicals. The aim of this review is to summarize the adsorption capacities for organic and inorganic pollutants by different bio-waste-based adsorbents.
