“…Parmi les deux formes les plus stables (i.e. Cr trivalent et Cr hexavalent), le Cr (VI) représente la plus grande menace pour l'environnement et la santé humaine, compte tenu de sa grande toxicité et son potentiel carcinogène (SHANKER et al, 2005). De plus, l'exposition répétée et/ou prolongée à cet élément chimique peut causer des diarrhées, des ulcères et des irritations de la peau et des yeux (TEWARI et al, 2005).…”

Les fibres du végétal marin Posidonia oceanica (L.) ont été utilisées en tant que nouvel adsorbant biologique pour l’élimination du chrome hexavalent des solutions aqueuses artificiellement contaminées. Les expériences ont été effectuées en lots aussi bien pour les cinétiques que pour les isothermes d’adsorption. Les variables expérimentales étudiées sont le pH, la température, la quantité de biomasse et la concentration initiale de Cr(VI). Le maximum de biosorption a été observé pour un pH 2. La capacité de biosorption semble être optimisée par une augmentation de la température, de la quantité de biosorbant et de la concentration initiale. Les isothermes d’adsorption sont en accord avec les modèles de Redlich-Peterson et Langmuir. De plus, l’analyse thermodynamique a révélé que le présent processus d’adsorption est un phénomène favorable, endothermique et spontané.The marine biomass Posidonia oceanica (L.) fibres were used as a novel low cost biological adsorbent for the removal of hexavalent chromium from artificially contaminated aqueous solutions. Experiments were carried out for sorption kinetics and isotherms in a batch system. The operating variables studied were pH, temperature, biomass quantity and initial chrome concentration. The maximum adsorption removal was observed at pH 2. The biosorption capacity of P. oceanica fibres for Cr(VI) was enhanced by increasing the temperature, the biosorbent amount and initial chromium concentration. The isotherm adsorption data were satisfactorily found to be described by both Redlich-Peterson and Langmuir. Besides, the thermodynamic studies revealed that the present adsorption process is a favourable, endothermic and spontaneous phenomenon

Abstract-No study have existed on heavy metals present in the river of Iloilo Batiano, Philippines. Thus, this study was conducted to determine the presence and quantities of heavy metals specifically cadmium, chromium and lead in the sediments of Iloilo Batiano River. Furthermore, water physicochemical parameters were determined such as pH and temperature, in situ. Three sampling stations were identified adjacent to (1) Batiano Bridge of Oton, Iloilo; (2) Sto. Niño Bridge of Villa, Iloilo City and (3) Calumpang Bridge of Molo, Iloilo City, respectively. Three (two sides and at the center perpendicular to the river) 500 g surface sediments were collected in each of the sampling station for a total of nine sediment samples stored in a sterile ziplock and were immediately transported at the CAS-ASL of UPV, Miag-ao, Iloilo for the quantification of metals through flame atomic absorption spectrophotometry (FAAS). Available cadmium was below detection limit and it appeared that available Pb > Cr in the three points of the river in the three sampling stations. Available chromium and lead have high accumulation in station three (Calumpang Bridge). This study provides information on the heavy metal status of the river, awareness to the public and for further conservation of the river.
