Preparation and Adsorption Properties of Strontium Tungstate Microspheres
Strontium tungstate microspheres were synthesized with sodium tungstate and strontium chloride as raw materials and water as medium,and a series of characterization of the prepared strontium tungstate microspheres were carried out.The adsorption properties of methylene blue dye were studied by using microsphere strontium tungstate as adsorbent.The adsorption properties were compared by changing the influence factors such as pH value,input dose,initial solution concentration,temperature and time.The absorbance of methylene blue dye was measured by ultraviolet visible spectrophotometer.The adsorption capacity and removal rate were calculated by fitting.The results showed that under the conditions of pH value of solution 2,dosage of 0.25 g,temperature of 75 ℃ and concentration of adsorption solution 5 mL,the adsorption effect of MB dye solution was the best.
