Resumen

En este estudio, se propone una técnica de precipitación de carbonato inducida por enzimas con bajo contenido de amonio (LA-EICP) que utiliza la capacidad de intercambio catiónico de la zeolita para eliminar el amonio, un subproducto de la hidrólisis de la urea perjudicial para el medio ambiente. El proceso LA-EICP es una precipitación de carbonato inducida por enzimas modificadas (EICP) adecuada para la estabilización de suelos, mediante la mezcla de zeolita y la solución resultante de hidrólisis de urea. Las cantidades de carbonato de calcio precipitado y los iones de amonio eliminados por la zeolita sintética modificada con calcio se analizaron a través de pruebas de precipitación en tubos. Además, se midieron y compararon las resistencias a la compresión no confinada de las muestras de suelo para investigar el efecto de refuerzo de LA-EICP. La precipitación de carbonato de calcio dentro de la muestra de suelo también se confirmó mediante análisis de microscopía electrónica de barrido y espectrometría de dispersión de energía. Los resultados mostraron que LA-EICP puede precipitar la misma cantidad de carbonato de calcio que el EICP convencional, mientras elimina casi todos los iones de amonio. Además, la muestra tratada con LA-EICP mostró un mayor aumento de la resistencia que la muestra tratada con EICP convencional, debido al efecto combinado del carbonato de calcio y la zeolita.
