“…The fruit stones are rich in lignocellulose which provides a suitable base structure for the production of activated carbons. The range of fruit stones and related materials studied include apricot stones [120], date stones [121], plum stones [122][123][124], peach stones [125][126][127], cherry stones [128][129][130], olive stones [131], Macore fruit [132] and corn cob [118,[133][134][135].…”

Olive stones have been widely used as a renewable energy biowaste source. As they are rich in elemental carbon (40-45 wt%), much research focussed on effectively converting olive stones, as precursors, into activated carbon adsorbents. However, only a few studies have concentrated on summarising the various techniques used to produce activated carbon from olive stone. This article reviews the research undertaken on the production and application of activated carbon as an adsorbent from olive stones for wastewater treatment. Various physical, chemical and physico-chemical treatments to remove heavy metals, organics and dyes are discussed, and the resultant adsorption capacities are reported. In several cases, very high adsorption capacities are recorded. Finally, the future prospects of these materials as adsorbents are discussed, and after further development work, olive stone-derived activated carbons have great potential especially in the area of organic polluted wastewaters.

“…Consequently, raw date stones possess considerable potential to be successfully activated, requiring only a small amount of energy for drying. A number of publications have reported the results of activating date stones with various activating agents and at various temperatures (Girgis and El-Hendawy 2002;Merzougui et al 2011;Suresh Kumar Reddy et al 2013;Danish et al 2014;Cherik and Louhab 2017). In order not to duplicate previous work and focus this study on the water treatment application, optimum literature criteria were selected to provide a high surface area at a relatively low temperature for keeping energy costs low.…”

“…Palm kernel shell was used to investigate the adsorption of three pharmaceuticals (To et al 2017), namely, atenolol, acebutolol and carbamazepine with adsorption capacities of 154, 165 and 154 mg/g respectively. Some studies have reported the production of activated carbons from date stones often termed date pits (Merzougui et al 2011;Danish et al 2014) using phosphoric acid (Girgis and El-Hendawy 2002), zinc chloride (Cherik and Louhab 2017) and carbon dioxide (Suresh Kumar Reddy et al 2013). The methodologies of converting date stones into activated carbons have yielded a variety of pollutant removal applications for this material, such as, pesticides (Hameed et al 2009;Hassan et al 2020), dyes (Al-Ghouti et al 2010Bouchemal et al 2012;Messaoudi et al 2016), heavy metals (Al-Ghouti et al 2010;Bouhamed et al 2012;Mangwandi et al 2020) and pharmaceuticals (Belhamdi et al 2016;Darweesh and Ahmed 2017).…”

Pharmaceutical products in water, frequently referred to as personal pharmaceutical products, PCPPs are regarded as problematic emerging pollutants with the potential to cause damaging health and environmental impacts to several ecosystems. In this study, an acid activated carbon has been produced from waste date stones, the waste product obtained from the seedless date products manufacturing industry. This material has been used to remove the pharmaceutical compound ibuprofen from water with a high adsorption capacity of 126 mg ibuprofen per g waste date stone derived activated carbon. In order to optimise the use of the activated carbon, a design study has been performed to minimise the quantity of carbon needed using a two-stage batch adsorption system. Several variables have been inputted into the design model to test the model and compare the quantities of adsorbent required in the two-stage and the single stage systems under various conditions.

Pharmaceutical products in water, also known as personal pharmaceutical products or PCPPs, are developing contaminants that have the potential to impair human health and the environment in a variety of ecosystems. In this work, waste date stones, a waste product obtained from the seedless dates manufacturing industry, were used to make acid-activated carbon. This material has been utilized to extract the medicinal component ibuprofen from water, with a high adsorption capacity of 126 mg ibuprofen per g of waste date stone-generated activated carbon. A design study was conducted to minimize the amount of activated carbon required, utilizing a two-stage batch adsorption system to optimize the usage of the activated carbon. To test the model and compare the quantities of adsorbent required in the two-stage and single-stage systems under various conditions, several variables were entered into the design model.
