简介
The demand of reactive nitrogen (N), such as ammonium (NH4+) and nitrate (NO3−), continues to increase for fertilizer applications as the population grows, but the Haber Bosch (Hsingle bondB) process currently employed for industrial N fixation is challenged by low efficiency and high energy consumption. Here we report on the investigation of ZSM-5 as a superior sorbent for the recovery of ammonium from aqueous solutions. Fast capture and release of ammonium (NH4+) have been achieved with >90% overall efficiency of recovery using synthetic solutions of NH4Cl and NaCl, respectively. The ZSM-5 sorbent has also been found to be recyclable and sustain high recovery efficiencies after multiple capture-release cycles. The capture of N has been further studied systematically in dependence of the dose of sorbent and reaction temperature, based on which the mechanism, thermodynamics and kinetics of ion …
