氢氧化铁胶体

研究了pH值、铁与砷的量比和初始砷浓度等因素对用氢氧化铁胶体吸附去除砷的影响，确定了最佳吸附条件。

Effects of the pH value , the iron / arsenic ratio , the initial concentration of arsenic , and some other factors on the arsenic adsorption by ferric hydroxide colloid were studied with optimal condition for As (ⅴ) and As (ⅲ) adsorption determined .

磁场对氢氧化铁胶体ζ电位的影响

The Effect of Magnetic Field on ξ Potential of Ferric Hydroxide Colloid

本文研究了磁场对氢氧化铁胶体ζ电位的影响。

In this paper , the effect of magnetic field on ζ potential of ferric hydroxide colloid is studied .

实验发现，氢氧化铁胶体的电泳速度随温度的升高而增加，但其？电势几乎与温度无关。

According to the experimental results , the electrophoresis rate of ferric hydroxide increases with temperature . However ,? potential of ferric hydroxide is nearly independent of temperature .
