摘要：

Magnetic field (MF) (B = 0.4 T) effects were studied on CaCO3 precipitated from Na2CO3 and CaCl2 solutions, which at 30degreesC were exposed for 30 min to the field. One of the impurity ions Mg2+, Zn2+, Fe2+, SO42-, HPO42- at 10(-5) mol l(-1) concentration was also added to CaCl2 or Na2CO3, respectively. The changes of zeta potential, pH and light absorbance (at lambda = 543.2 nm) of the slurry after CaCO3 precipitation were measured on the time. In some experiments changes in the deposited amounts of CaCO3 due to MF treatment were determined on glass plates. MF affected all the parameters measured and the effects depended on the kind of impurity ion present.
