Boron removal from geothermal waters by electrocoagulation

Electrocoagulation of Azo-2-Naphthol Dye Using Aluminium Electrodes: Effect of Solvent and Kinetics of Adsorption

“…Similar pseudo-second order kinetic models have been reported in the adsorption of phosphate on Fe (III)/Cr (III) hydroxide (Namasivayam and Prathap, 2005), NO 3 G on iron (III) hydroxides adsorbents (Ghanim and Ajjam, 2013) and removal of cadmium ion on aluminium electrodes (Mansour et al, 2013). Boron removal from synthetic wastewater also followed pseudo-second order model (Yilmaz et al, 2008b).…”

Niveles de boro no permisibles en reservorio de agua potable, cuenca hidrográfica Locumba, región Tacna, Perú

“…El boro es un microelemento esencial para las plantas (Yilmaz, Boncukcuo ǧ lu, Kocakerim, Yilmaz & Paluluo ǧ lu, 2008) como para los animales (Dydo, Turek, Ciba, Trojanowska & Kluczka, 2005), aunque en la actualidad, sigue siendo un tema de interés y debate su efecto perjudicial (Mustafa & Sirri, 2013). A pesar que las concentraciones permisibles varían de un país a otro (Hilal, Kim & Somerfield, 2011), la Organización Mundial de la Salud (2011), refiere que entre 0,1-0,3 mg.L -1 oscilan las concentraciones en agua potable, asignando un valor de referencia provisional de 0,5 mg.L -1 , así como 2,4 mg.L -1 para el consumo humano (Tagliabue, Reverberi & Bagatin, 2014).…”

Mechanisms of boron removal from hydraulic fracturing wastewater by aluminum electrocoagulation

“…Although boron is essential for plant growth and is a possible human trace nutrient, chronic exposure even at low doses causes testicular atrophy, decreased survival, and developmental and reproductive toxicity in animals [5]. Some crops such as blackberry are sensitive to even low (<0.5 mg/L) levels of boron while many other fruits and vegetables experience toxicity at concentrations >0.5 mg/L [6,7]. Boron containing viscosity modifiers also need to be removed from the flowback/produced water to make the reused water compatible with ''gel-frac'' formulations to fracture subsequent wells [1].…”
