“…The most dynamic and thorough requirements for ACs in purification methods are connected to the contented of inorganic constituents [34]. AC for gas and air purification has a BET surface area between 800 -1500 m 2 per gram, where for water purification within the range of 500 to 1500 m 2 /g [35].…”

Activated carbon (AC) is an extremely porous carbonaceous adsorptive substance which has a rigid carbon matrix with high surface area and broad functional groups. The structure is connected by chemical bonds; arranged irregularly, generating a highly porous arrangement of corners, crevices, claps, and cracks between the carbon layers. Activated carbons are produced high-temperature and chemical activation of waste biomass. The pores in the lattice network of activated carbon permit the removal of impurities from gaseous and liquid medium through adsorption. At present, the COVID-19 disease is the prime concern around the whole world because of its exponential infections and death rate. There is no medicine for this virus, and protection is the only remedy to survive from this contagious disease. Using a face mask is one of the best methods to get rid of COVID-19. The mask combined with activated carbon can be beneficial for adsorbing and disinfecting the virus as it is the versatile adsorbent for the elimination of the organic, inorganic, and pathogenic contaminants.

Currently, wastewater containing heavy metals treatment has been included as a significant topic for research. This is due to the effluent that is concentrated with a toxic and hazardous content which needs for a proper treatment as to reduce the environmental impacts before it can be released as an effluent. Therefore, biosorption by waste material was proposed in this study as a treatment method for this type of wastewater. The objective is focus on the comparison of the characteristics and performance of raw eggshell waste biosorbent with prepared hybrid eggshellpandan biosorbent on the removal of Cr (VI) ions in aqueous solution. From the study, it showed that the prepared hybrid biosorbent perform higher percentage in the removal of Cr (VI) ions in aqueous solution compare to the raw eggshell waste with its optimum condition at 140 min of contact time, 0.5 g of biosorbent dosage at 50 °C and pH 4 in 0.8 mg/L of solution concentration. On the other hands, the optimum conditions for the raw eggshell waste biosorbent to achieve its highest percentage removal of Cr (VI) ions in aqueous solution is 140 mins of contact time, 0.5 g of biosorbent dosage in room temperature at pH 5 in 0.8 mg/L of solution concentration. The kinetic study revealed that the adsorption model of this study follows the pseudo-second-order kinetic model of Legergren with positive value of enthalpy (16.68 kJ/mol) and entropy change (0.0473 kJ/mol). In addition, hybrid eggshell-pandan biosorbent has a potential to become a candidate of biosorbent to the removal of Cr (VI) ions in wastewater.

“…This activation produces a porous material with a large surface area ranging from 500 to 1500 m 2 g −1 and a high affinity for pollutants from gas or liquid streams (Rahman et al 2006 ). It is now applicable in many fields of operation, particularly on a commercial scale for a number of purposes such as effluent treatment (Yusufu et al 2012 ; Marichelvan and Azhagurajan 2018 ), water purification (Ademiluyi et al 2009 ; Sivakumar et al 2012 ; Hegazi 2013 ; Ijaola et al 2013 ; Ukpaka and Edwin 2013 ; Abraham et al 2018 ), pesticide adsorbent (Gokhale et al 2020 ), and heavy metal sorption (Ijaola et al 2013 ; Mopoung et al 2015 ; Elelu et al 2019 ; Özsin et al 2019 ). It is also applicable in medicine for removal of poisons (Wang et al 2010 ) and recently, as filter in nose masks for the prevention against novel Coronavirus SARS-CoV-2 (Reza et al 2020 ).…”

Hamburger seed coat is a readily available agricultural waste product generated in large quantities annually. In this study, activated charcoal was produced using hamburger seed coat activated with zinc chloride and its physicochemical properties such as fixed carbon, specific surface area, volatile matter, ash and moisture content were investigated. Scanning electron microscopy and Fourier transform infrared spectrometry techniques were used to study the surface morphology and variations in the absorption bands of functional groups, respectively. The adsorbent biosorption of pollutants abilities from contaminated water was investigated using standard methods with a view to ascertaining the adsorbent purification potential. The results showed that the adsorbent was of high porous structure with adsorption capacity significantly correlated with iodine value. The physicochemical properties of the contaminated water treated with the adsorbent were comparable with commercial activated charcoal (control)-treated water but indicated a significant decrease ( p < 0.05) in the pH, temperature, total dissolved solids, total suspended solids, conductivity, turbidity, alkalinity, hardness, biochemical oxygen demand, chemical oxygen demand, anions and heavy metal ions when compared to the untreated water. With the exception of alkalinity, other parameters investigated in the water treated with the test adsorbent fell within the standards set for potable water. Results of this study therefore revealed possibility of converting large quantities of hamburger seed coat wastes that could constitute environmental pollution to a profitable product that could be employed for treatment of wastewater.
