“…2. Corresponding major element concentrations of these samples, as previously reported by Hacini et al (2008) are provided in Appendix 1. These concentrations are shown as a function of time from January, when the chott water volume near a maximum until June when the chott lake completely evaporated and infiltrated.…”

“…The Chott Merouane is located *31 m below sea level, the lowest location in northwest Africa. The annual geochemical and hydrologic evolution of this chott was characterized in detail by Guendouz et al (2003), Hacini et al (2006), and Hacini et al (2008). This chott is an outlet for the Terminal Complex aquifer, which brings in water from the north, west, and south.…”

“…The hydrology of the Merouane Chott was described by Hacini et al (2008). There are three major inputs of water to this chott: groundwater springs emitting water from the Terminal Complex aquifer, the Oued Righ canal, and rainwater.…”

“…The total annual water volume added to the Merouane Chott during 1994, equal to the sum added by the groundwater springs, Oued Righ canal, and rainfall is estimated to be 198 9 10 6 m 3 . The total volume of water present in the chott during the first half of 2003 estimated from aerial photographs ranged from 92 9 10 6 m 3 in February to 0 in late June (Hacini et al 2008). The major H 2 O outlet during this time is evaporation, which depends strongly on the ambient temperature.…”

The Merouane Chott, located in arid southeastern Algeria, experiences annual cycles of filling from September through February followed by its complete evaporation from February through June. The concentration of 15 trace elements (Li, B, Ti; V, Cr, Mn, Co, Cu, Ni, Zn, As, Sr, Ba, Pb, Bi, and U) were measured in chott water samples collected from January through June 2003 during the complete evaporation of the lake. The corresponding concentrations of these trace elements in the major external inputs to this closed basin chott were also obtained. The trace metals show two distinct behaviors. Li, B, Cr, Co, and U tend to be conserved in the chott waters throughout its evaporation. Much of Cr, Co, and U originated from external sources. It is likely, therefore, that the concentration of these elements will increase in the chott waters in future years. In contrast, Ti, Sr, Ba, Zn, Ni, and Pb precipitate continuously during chott evaporation. Of these elements, most of the Sr, Ba, and Zn originated from outside the chott, and thus it is likely these elements will become increasingly concentrated in the chott bottom salts with time. V, As, and Cu exhibit intermediate behaviors. These contrasting behaviors are confirmed by analysis of chott bottom solids.

Southern Algerian's natural brine sampled from chott Baghdad may be a source of mineral salts with a high economic value. These salts are recoverable by simple solar evaporation.Indeed, during isothermal solar evaporation, it is possible to recover mineral salts and to determine the precipitation sequences of different salts as a function of the chemical composition and the density of the brine. In this study, the variation of ionic composition of concentrated brine during isothermal evaporation was measured; then the experimental pathway of the point representing its composition on the oceanic fivefold diagram Na + , K + ,2-//H 2 O was plotted. In order to follow the precipitation sequences of mineral salts, during solar evaporation at 35°C, X-Ray diffraction was performed on the precipitated and removed salts from the brine during evaporation.
