“…CSAC had some of the pores partially blocked. Prominent bright silver patches were seen on the surface of PKCAC suggesting the presence of iron oxide which is in line with the study reported by [8]. The high porosity of PKCAC is known to increase adsorption capacity [5].…”

“…This observation was also corroborated by [10]. The increase in surface area of the adsorbent and the availability of active sites are believed to be responsible for the rapid adsorption of metal ions at the beginning stage of the reaction [8].…”

“…2 a, b, c and d established the presence of different peaks corresponding to different functional groups along the wavelength 4000-640 cm -1 . All the activated carbons except CSAC showed strong peaks between 3000-3700 cm -1 which suggest the presence of O-H stretching vibrations of water moieties [5], [8]. PKCAC and CSAC have peaks between 2600-2900 cm -1 which correspond to C-H stretching vibrations from methyl group [9], [7].…”

This study investigated the removal of Lead and Cadmium ions from aqueous solution using activated carbons from agricultural wastes. Activated carbons prepared by chemical activation using Phosphoric acid were characterized by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and Brunauer-Emmett-Teller (BET) analysis. The influence of contact time, initial concentration and adsorbent dose which governed the efficiency of the process was ascertained through batch adsorption studies. Adsorption isotherms were determined by correlating with Langmuir and Freundlich isotherms and the kinetic studies were correlated with pseudo first order and pseudo second order equations. The results showed that the amount of Lead and Cadmium adsorbed decreased as the adsorbent dose increased while the adsorption capacity increased with increased in contact time and initial concentration. Activated carbons prepared from Coconut shell and palm kernel (shell and cake) competed favorably with the commercial activated carbon in percentage removal of the metal ions as all the activated carbons had over 90 % removal within 60 minutes when 1g of adsorbent was used. The equilibrium data fitted best into Freundlich isotherms for both metal ions. The rate of adsorption could be described by pseudo second order for all the adsorbents except Coconut shell activated carbon in the adsorption of Lead while intra-particle diffusion was the limiting step for Cadmium adsorption. Therefore, the agricultural by-products can be used as effective, low-cost, and environmentally friendly adsorbents for domestic water treatment in many parts of the world.

“…Zeolite is another commonly available commercial adsorbent. Zeolite is an inorganic substance with high porosity, wide surface area, high regeneration potential, strong acidic stability, and economics, making it a good adsorbent for OW treatment [54]. Jun et al [54] reported that zeolite is exceptional for removing organic compounds and heavy metals in wastewater.…”

Oil-contaminated or oily wastewater (OW) is generated from various industrial and domestic premises. It consists of fats, oils, and greases and may contain petroleum fractions such as diesel oil, gasoline, and kerosene. It is regarded as one of the most hazardous wastewaters, causing serious environmental and health threats to ecosystems and human beings. The global increase in the discharge of OW coupled with stringent regulations for effluent discharge and incessant drive for the reuse of treated wastewater necessitate the need for the treatment of the OW. Conventional approaches employed in the past are inept for OW treatment due to low separation efficiency, high operational cost, creating secondary pollution, and long treatment hours. Comparatively, the adsorption process is considered a better alternative because of its simple design and can involve low investment in terms of both initial cost and land required. Thus, the adsorption process is widely applied as a promising alternative to existing treatment methods for OW. The adsorption process is an effective technique for OW treatment. Super adsorbents with ultrahigh adsorption capabilities are highly desired for efficient OW treatment in a new revolution of adsorption technology to meet present and future needs. This review provides insights into advanced and emerging state-of-the-art technologies of the adsorption process as a safe and efficient treatment of OW. Strength, weakness, opportunities and threats (SWOT) analysis was conducted to identify and analyze internal strengths and weaknesses and external opportunities and threats that shape the current and future operation of the adsorption process for the treatment of oily wastewater for developing strategic goals. Super adsorbents with ultrahigh adsorption capability such as P-GSC and P-PKS discussed are highly desired. The extraordinary properties of P-GSC and P-PKS can provide leap-forward opportunities to revolutionize traditional adsorption technology. However, scale-bridging and optimization study of these innovated super adsorbents is required for the real application. It shows a bright future of P-GSC and P-PKS towards OW treatment.

“…It is mostly preferred due to Yuan et al (2011) its direct application, simplicity and low processing costs (Ahmad et al 2005a,b & c;Sokker et al 2011;Izevbekhai et al 2020). Application of natural biosorbents for the removal of pollutant load in oily wastewater has been studied (Ibrahim et al 2010;Jun et al 2020). Devi et al (2012) employed low molecular weight crab shell chitosan as adsorbent for the treatment of vegetable oil mill effluent.…”

Oily wastewater consists of fats, oils and greases together with a broad spectrum of dissolved organic and/or inorganic substances in suspension. It is regarded as one of the most hazardous wastewaters, causing serious environmental and health threats to the ecosystems, flora and fauna. The global increase in the discharge of oily wastewater coupled with stringent regulations for effluent discharge and incessant drive for re-use of treated wastewater necessitate the need for treatment of the wastewater. Conventional approaches employed in the past are inept for oily wastewater treatment due to low treatment efficiency and high operational costs, among others, hence the need for adoption of advanced technologies as promising alternatives to existing treatment systems for oily wastewater. Furthermore, the use of combined treatment processes is effective for the removal of hazardous pollutants present in high-strength oily wastewater. This review provides insights into advanced and emerging state-of-the-art technologies for safe and efficient treatment of industrial oily wastewater.
