【 摘 要 】

The scale of ferrous carbonate (FeCO3) deposited on the pipe wall was investigated in the present study. In the experimental work, the scale-forming solution was prepared by mixing equimolar solutions of FeCl2 and Na2CO3. Zeolite is used as an adsorbent because it has a crystal structure of alumina silica with cavities containing metal ions Fe2+. It was found that in all the experiments, the mass scale FeCO3 decreased with increased mass zeolite adsorbance addition. The mass scales obtained in the presence of 4000 mg zeolite was 14.2613 mg of FeCO3. Similarly provided 22.1642 mg of mass scale was found in the presence of 3000 mg zeolite. The increasing mass scale 34.2652 mg was also produced at 2000 mg zeolite. Clearly the zeolite adsorbation may be used to improve the scale produced. The conductivity decreased abruptly after a certain induction period. The induction time was observed in the FeCO3 system almost doubled in the presence of 2000 mg zeolite (28 min), tripled with 3000 mg zeolite (42 min). Moreover, the presence of 4000 mg zeolite (44 min) led to an induction time four times greater than that for in the absence of zeolite system (22 min). The optimum result of temperature was 44.6390C, zeolite was 3625.068 mg variables was obtained so that the optimum the mass scale FeCO3 was 14.46187 mg.
