“…Furthermore, the pH of the point of zero charge pH pzc for LPw was found equal to 4.6. The surface of LPw was then positively charged for pH values below 4.6 and negatively charged for values above 4.6 31.…”

“…The samples were then degassed for 6 h at 363 K on a Quantachrome NOVA 1000 instrument. The BET method was employed to calculate the specific surface area within a range of relative pressure ( P / P 0 ) ranging from 0.05 to 0.35 31, 32.…”

“…The physicochemical characterization of the second biosorbent, i.e., the PDw, was carried out through the determination of the specific surface by the Brunauer-Emmett-Teller (BET) method, the pore diameter by the Barrett-Joyner-Halenda (BJH) method, the pH corresponding to the point of zero charge (pH PZC ), and functional groups by the Boehm method and Fourier transform infrared (FTIR) spectroscopy. The LPw has been previously characterized by several procedures [31].…”

Pistachia lentiscus (LPw) and date palm leaves (PDw) are two biosorbents that are mainly used for the removal of chromium and cobalt from an aqueous solution. These biosorbents were characterized by physicochemical procedures, including Fourier transform infrared spectroscopy, zero charge point, Boehm method, and Brunauer‐Emmett‐Teller (BET) method. Various parameters, such as contact time, biosorbent quantities, diameter of the biosorbent particles, ionic strength, initial pH, and initial concentration of solutions, were optimized. The reactions of PDw+Co, LP+Co, and LPw+Cr exhibited similar isotherm profiles of type L, but indicated isotherm type C in the reaction PDw+Cr profile, according to the BET classification. All reactions mentioned above were described by the Freundlich and Temkin adsorption isotherm models, with R2 greater than 0.97. The kinetics most likely followed the pseudo‐second‐order model which was confirmed by error calculation.
