钛在工业和国防上的用途广泛,其生产性废水可能会污染水源水质。我们采用国际标准实验生物大型溞对钛离子的毒性进行了研究,为制订水质卫生标准提供依据。1 材料和方法四氯化钛:广东台山兴塔化工厂生产,按离子浓度配制。实验用稀释水按国际标准组织(ISO)人工配制标准水。实验水温恒定在20℃±0.5,pH7.6±0.2。实验用大型溞:选用中国预防医学科学院环境工
Titanium has many uses in industry and defense, and its productive waste water may pollute water quality. We use the international standard experimental biological large-scale toxicity of titanium ions were studied to provide the basis for the development of water quality standards. 1 Materials and Methods Titanium tetrachloride: Guangdong Taishan Xingtai chemical plant production, prepared by ion concentration. Experimental dilution water according to the International Organization for Standardization (ISO) manual preparation of standard water. The experimental water temperature is constant at 20 ℃ ± 0.5, pH7.6 ± 0.2. Experiment with large 溞: Selection of Chinese Academy of Preventive Medicine Environmental Engineering
