The early evaluation of urea content in water and wastewater is of utmost importance for preventing pollution and improving remediation technologies, also related to urea conversion into a valuable energy product. In this work, a customized urease-based potentiometric platform for the detection of urea in wastewater samples was developed. Amino-functionalized glass beads were used as support material for urease immobilization in a customized bioreactor
then, using an online flow measurement setup, the NH
