The presence of phosphate in wastewaters can cause eutrophication of surface water bodies leading to algal-blooming in the aquatic environment and degradation of water quality. Phosphate removal from wastewaters by conventional biological treatment removes only 10-30% of the phosphate, whilst chemical treatment using precipitants such as calcium or iron salts, although effective, is expensive and produces water-rich sludge which must be further treated. Hence, phosphate removal by adsorption in the form of Ca-phosphate has been proposed as an alternative to the more traditional methods. This study investigated the feasibility of using dolomite-a common sedimentary rock-from Padalarang, West Java, Indonesia as the adsorbent for the removal of phosphate from synthetic aqueous solution. Chemical analysis revealed that the Padalarang dolomite contains 33.6-36.2% CaO. Batch experiments at room temperature indicated that optimum removal of phosphate was achieved at pH 9. At 25°C, where increasing concentrations of phosphate (10-100 mg/L) increased phosphate adsorption (2.15-31.3 mg/g) by the dolomite. The adsorption of phosphate could be described by the Langmuir isotherm model, with constants Q m = 476.19 mg/g, K L = 0,00106 L/mg and equilibrium parameter (R L): 0.904-0.989. Phosphate adsorption by dolomite not only permits its removal but also its potential recovery for reuse.
