Arsenic and metal mobility from Au mine tailings in Rodalquilar (Almaría, SE Spain)
(2010-02-19)
Article
Restricted access - publisher's policyIn the old mining area of Rodalquilar, mine wastes, soil and sediments were characterized and the results revealed high concentration of Au, Ag, As, Bi,Cu, Fe, Mn, Pb, Se, Sb and Zn in tailings and sediments. The contaminant ... -
Development of iron oxide based sorbents for arsenic stabilization in contaminated soil
(Universitat Politècnica de Catalunya, 2012)
Bachelor thesis
Restricted access - author's decisionHigh arsenic level in natural waters, and in the ground, is nowadays a worldwide problem. Soil stabilization is a low-cost technology aiming to reduce the arsenic mobility in soil preventing the migration of the contaminant ... -
Electrodes modification with silver nanoparticles for the detection of arsenic
(Universitat Politècnica de Catalunya, 2017-10-05)
Master thesis
Open AccessL'arsènic és un dels 10 productes químics de l'OMS (Organització Mundial de la Salut) de major preocupació per la salut pública. El límit actual recomanat d'arsènic a l'aigua potable és de 10 ppb. Les tècniques habituals ... -
Estudi de la qualitat i ús d’aigües freàtiques urbanes en el riu Besòs i el seu tractament de millora mitjançant carbó actiu i/o ultrafiltració
(Universitat Politècnica de Catalunya, 2019-10-23)
Master thesis
Open AccessEn aquest treball s’estudia experimentalment l’adsorció d’arsènic amb els adsorbents Bayoxide E33 i Lewatit FO 36 i l’adsorció de manganès amb pirolusita. Els resultats experimentals s’ajusten a les isotermes de Freundlich ... -
Estudio de la detección de As(V) mediante sensores modificados con nanopartículas de plata y su eliminación con micropartículas de hierro
(Universitat Politècnica de Catalunya, 2021-07-06)
Bachelor thesis
Open AccessEl arsènic actualment és un dels 10 productes químics de l’OMS (Organització Mundial de la Salut) de major preocupació pública. Amb un límit recomanat realment baix, 10 ppb, segueix sent un gran perill per a aquells que ... -
Evaluación de la movilización del As procedente de los residuos mineros abandonados de una zona semiárida (Rodalquilar, Almería)
(2015-08-24)
Article
Open AccessSe han realizado trabajos de campo y estudios de laboratorio así como un modelo matemático de simulación a fin de evaluar la movilización del As a largo plazo a partir de un depósito de residuos, que se encuentra junto a ... -

Immobilisation of Arsenic in Anaerobic Environment
(Universitat Politècnica de Catalunya / Luleå Tekniska Universitet, 2009)
Master thesis (pre-Bologna period)
Restricted access - author's decisionNowadays, the main method applied to remediate As contaminated soil is excavation and landfilling. Soil treatments normally are implemented under aerobic conditions. This study was conducted to investigate the possibility ... -
Increasing sustainability on the metallurgical industry by integration of membrane nanofiltration processes: acid recovery
(2019-11-01)
Article
Open AccessThe metallurgical industry generates large volumes of toxic effluents characterised, generally, by high acidity and a noticeable content of metals (Fe, Cu and Zn) and non-metals (As, Sb, Bi). The toxicity of these streams ... -
Increasing the circularity of the copper metallurgical industry: Recovery of Sb(III) and Bi(III) from hydrochloric solutions by integration of solvating organophosphorous extractants and selective precipitation
(2023-02-01)
Article
Open AccessThe lack of high-purity ores has made the copper industry exploit low-impurity ores containing As, Sb and Bi which can affect the final product quality due to the floating insoluble arsenates. This is usually solved by ... -
Spatial assessment of soil pollutants: a compositional approach
(Universitat Politècnica de Catalunya, 2017-06-15)
Master thesis
Restricted access - author's decisionThe present project is aimed to study the spatial variability of the As concentration within Northern Ireland. The main objective has been to assess the risk of high concentration of As in the soil within the domain of ...
