Caractérisation d’une latérite naturelle du Burkina Faso en vue de l’élimination de l’arsenic (III) et l’arsenic (V) dans les eaux souterraines

Abstract: RÉSUME L'arsenic est l'un des principaux polluants des eaux de forage, et constitue une des préoccupations internationales en raison de ses effets néfastes sur la santé humaine. Dans cette étude un matériau latéritique a été utilisé pour l'élimination de l'arsenic (III) et l'arsenic (V) dans une solution aqueuse. La latérite utilisée est référencée DA et caractérisée par différentes méthodes physico-chimiques (DRX, FTIR, analyse chimique élémentaire, MEB). La caractérisation a permis la quantification des miné… Show more

“…Among all of these approaches, adsorption has been proven to be the most promising method because of its high efficiency, ease of handling, and the availability of several types of adsorbent materials. Among these adsorbents, natural laterites have been the subject of many investigations since they were shown to have potential applications in arsenic removal from groundwater [18][19][20][21][22][23][24]. In our context, natural laterites are widely available in the country and can be used for low-cost arsenic removal.…”

“…In our context, natural laterites are widely available in the country and can be used for low-cost arsenic removal. Indeed, many studies have documented arsenic removal by adsorption on natural laterite using the batch mode, as well as fixed-bed column systems [18][19][20][21][22][23][24]. In an effort to develop an efficient, low-cost, and easily applied method, our previous research focused on As(III) adsorption in the batch mode using local natural laterites [21,22].…”

“…In this context, several studies have invested in the search of effective materials (adsorbent) to clean up contaminated water. Ouédraogo et al showed that the properties of a laterite from Burkina Faso gave it an adsorbent power in the removal of arsenic [5]. Sawdust has been proven to remove unwanted material from water [6].…”
