磁性、分光光度、还原性和超离心实验表明，斜凤头虫和乳糜虫的钒细胞溶血物中的钒以三价硫酸钒的形式存在。430 μ m处的吸收峰是由水解离子V(OH)2+（或VO+）产生的。通过分光光度法测定发现，水解常数与硫酸盐离子浓度有关。
It has been shown by magnetic, spectrophotometric, reductometric, and ultracentrifugation experiments that the vanadium in vanadocyte hemolyzates fromAscidia obliquaandPhallusia mamillatais present as trivalent vanadium sulfate.The absorption peak at 430 mμ is due to the hydrolysed ion V(OH)2+(or VO+). The hydrolysis constant is found by spectrophotometric measurements to be dependent on the sulfate-ion concentration.
