overview | erbium chloride chemical formula ErCl3 · 6H2O. Molecular weight 381.73. Pink deliquescent crystals. Melting point 774 ℃, boiling point 1500 ℃. Soluble in water and acid, slightly soluble in ethanol. Heating in a hydrogen chloride gas stream to obtain anhydrous salt, the latter is light red or light purple flake crystals, slightly hygroscopic. It is less soluble in water than its hexahydrate salt. When the aqueous solution is heated, it gradually becomes opaque, and after dehydration, it becomes a mixture of erbium chloride and erbium oxychloride. It forms an adduct with hexamethylenetetramine. |
toxicity | the effects of erbium chloride and dysprosium chloride on mouse immune cells were studied by thiazolam (MTT) method. The results showed that erbium chloride at a concentration of 0.001,0.1,1 μmol/L inhibited the proliferation of mouse spleen cells, while erbium chloride at other test concentrations had no effect on the proliferation of mouse spleen cells. Except that dysprosium chloride with a concentration of 0.1 μmol/L had no effect on the proliferation of mouse spleen cells, other tested concentrations of dysprosium chloride promoted the proliferation of mouse spleen cells. within the test concentration range, the effect of erbium chloride on the proliferation of mouse T lymphocytes is as follows: inhibition-promotion-no effect-promotion; dysprosium chloride can promote the proliferation of mouse T lymphocytes, and with the increase of the concentration, its promotion effect is weakened. The effects of erbium chloride and dysprosium chloride on the proliferation of mouse B lymphocytes are similar. Erbium chloride with concentrations of 0.001 and 0.01 μmol/L has no effect on the proliferation of mouse B lymphocytes, while the same concentration of dysprosium chloride promotes the proliferation of mouse B lymphocytes. When the high concentration is 0.1 μmol/L, both erbium chloride and dysprosium chloride inhibit the proliferation of mouse B lymphocytes, and further increase the high concentration to 1, at 10 μmol/L, they all turned to promote the proliferation of mouse B lymphocytes. when the action time is 4h, both erbium chloride and dysprosium chloride can improve the activity of NK cells. when the action time is extended to 8h, their ability to improve the activity of NK cells is weakened, and even individual concentrations turn to reduce the activity of NK cells. The results suggest that the effects of erbium chloride and dysprosium chloride on immune cells in mice are related to their action time, concentration and types of rare earth compounds. |
