Wasted Low Grade Iron Ore with High Phosphorus Reuse for Phosphate Removal from Aqueous Solution by Using a Factorial Design

Abstract:

Low grade ore iron with high phosphorus (LGIOWHP) is used as an adsorbent to remove phosphate from aqueous solution. The orthogonal experiment of L₁₆ (4⁵) was used to study the effects of experimental parameters on the phosphate removal rate. The important degree of the effects of parameters on the phosphate removal rate is as follows: initial pH > stirring speed > reaction time > reaction temperature > adsorbent dosage. The results show that the phosphate removal rate exceed 99% under the conditions of pH 5.6, temperature 65 °C, reaction time 75 min, particle size <0.147 mm, initial phosphate concentration 20 mg/L, adsorbent dosage 60g·L^-1 and stirring speed 200 r·min^-1. After phosphate removal reaction, the phosphate concentrations completely meet the requirement of national discharge standards of the second category pollution (GB 8978-1996 ).
