Descripción
Two different adsorbents directed to nitrate removal from water were developed from Parkinsonia aculeata wood. An activated carbon was obtained by chemical activation with K2CO3 at 800 °C, whereas another adsorbent was prepared using a dilute solution of NH4Cl at 450 °C. Elemental compositions, surface functional groups, and textural parameters of both adsorbents were determined and compared with those of a commercial activated carbon used as a reference. Nitrate adsorption assays were carried out to examine the effects of solution pH, adsorbent dosage, contact time, and equilibrium adsorption isotherms. The adsorbent obtained with K2CO3 showed a well-developed pore structure (S BET∈=∈777 m2/g; V T∈=∈0.35 cm3/g) and neutral character, while the one prepared with NH4Cl exhibited a low porous development (S BET∈=∈58 m2/g; V T∈=∈0.03 cm3/g), acidic nature, and a noticeably high N content. The latter attained the highest nitrate removal efficiency, with a maximum adsorption capacity (X mL∈=∈0.40 mmol/g) higher than those estimated for the former (X mL∈=∈0.34 mmol/g) and the commercial sample (X mL∈=∈0.23 mmol/g), pointing to a predominant role of the chemical surface characteristics, mainly of N-containing groups and basic functionalities. Accordingly, the adsorbent obtained with NH4Cl represents a friendly novel material especially suited for nitrate removal.
