“…As a result, even 38% (w/w) cellulose solutions can be prepared (Boerstoel et al 2001). After the acid hydrolysis, the extraction of lignin can be performed from the residual liquid and solid phases (Horvath 2006;Tsubota et al 2015). Figure 2 depicts the changes originated in the structure of biomass by acid treatment (Hsu et al 1980;Kumar et al 2009).…”

The fabrication of activated carbon (AC) is widely carried out by the so-called chemical activation method, in which the biomass substratum is put in touch with an impregnating chemical agent prior to the carbonization stage. Even though this methodology is known for a long time, there are many features that are still poorly understood, particularly those regarding the details of the underlying mechanisms implied during the interaction of the activating agent with the precursor, eventually leading to the development of AC. Previous research conducted in the laboratiores dealt with the use of cherry stones (CS) and phosphoric acid, towards ACs with tailored porous structures, finding out that the experimental variables of the impregnation stage

“…Biochars are carbonized biomass, commonly used for soil and water treatment purposes. They have become popular as adsorbents thanks to their high porosity, adsorptive surface functionality, and the possibility of tailoring their properties for enhanced removal of specific pollutants [1][2][3]. In addition to promising adsorptive properties, biochar is relatively easy and cost-effective to produce from locally available biomass sources.…”

The modification process of biochars enables different advantages including enhanced adsorption properties for different pollutants. Herein, porous magnetic biochars (PMB) were successfully produced from softwood biomass through a two-step pyrolysis process together with FeCl3 modification. The effect of production temperature on adsorption was studied at 200 or 300 °C, followed by iron salt modification and subsequent pyrolysis at 600 or 800 °C. Biochars were characterized before and after phosphate adsorption via various characterization methods to acquire structural, elemental, and morphological properties of the adsorbent. The effects of phosphate concentration, contact time, and temperature on the adsorption process were examined in the batch mode. The characterization showed embedded iron oxide crystals of 23 nm within the biochar structure with a magnetic strength of 38.9 emu/g, which can assist the separation process of the powdered adsorbent from the aqueous medium. The surface area of the PMB was measured as 93 m2/g and 0.002 cm3/g pore volume. PMB showed complete removal (100%) of phosphate at the lower concentration (5 mg/l P). At higher concentration (25 mg/l P), the biochar prepared under 200/800 °C showed the highest removal (30%). The adsorption was enhanced with time (optimal 3 h) and temperature, which shows endothermic chemisorption following Langmuir isotherm and Pseudo-second order kinetic models. The desorption study suggested the slow release of phosphate from the spent adsorbent and potential reuse for soil enhancement. These results point towards the sustainable use of PMB as an effective and magnetically recyclable adsorbent for phosphate removal and reclaim.
