| description | The objective of the present investigation was to construct an electrocoagulation cell in a batch system and to evaluate its capacity to remove the anionic surfactant of the linear alkylbenzene sulfonate (LAS), which is present in gray water determining the effect of the type of electrodes (Al or Fe), distance between electrodes (1, 1.5 and 2 cm) and voltages (10, 15 and 20 V). The experimental tests were carried out for 20 min. The dimensions of the short wave electrolysis cell built in glass were 26 cm long, 7 cm wide and 12 cm high, with 10 electrodes of 12x6 cm supported by a PVC structure. The concentration of LAS in the solution was determined by employing UV-Vis spectrometry applying the Methylene Blue Active Substances (MBAS) method. A higher removal of 65.55% was obtained when aluminum electrodes were used, and 69.11% with iron electrodes a separation of 1.5 cm and a voltage of 20 V, presenting less change in pH, conductivity, and energy consumption when using the Al3 electrode. When evaluating the effect of time at the best experimental configuration (Al, 1.5 cm, 20 V) it was established that the removal efficiency increased to 75.13% in 60 min. Electrocoagulation with aluminum electrodes is presented as an efficient alternative for the removal of LAS in solution. |

El objetivo de la presente investigación fue construir una celda de electrocoagulación en sistema por lotes y evaluar su capacidad de remover el surfactante aniónico de tipo Alquilbenceno sulfonato lineal (LAS) presente en aguas grises determinando el efecto del tipo de electrodos (Al o Fe), distancia entre electrodos (1, 1.5 y 2 cm) y voltajes de (10, 15 y 20 V). Los ensayos experimentales se realizaron durante 20 min. Las dimensiones de la celda electrólisis de onda corta construida en vidrio fueron 26 cm de largo, 7 cm de ancho y 12 cm de alto, con 10 electrodos de 12x6 cm sostenidos por una estructura de PVC. Se determinó la concentración de LAS en la solución mediante espectometria UV-Vis aplicando el método el método de Sustancias Activas al Azul de Metileno (SAAM). Se obtuvo una mayor remoción del 65.55% cuando se usó electrodos de aluminio, y 69.11% con electrodos de hierro una separación de 1.5 cm y un voltaje de 20 V, presentándose menor cambio en el pH, conductividad y consumo energético al usar el electrodo de Al3. Al evaluar el efecto del tiempo a la mejor configuración experimental (Al, 1.5 cm, 20 V) se estableció que la eficiencia de remoción aumentó a 75.13% en 60 min. Se presenta la electrocoagulación con electrodos de aluminios como una alternativa eficiente para la remoción de LAS en solución.
