Abstract

The invention relates to a preparation method of potassium chloroplatinite. The preparation method mainly comprises the following steps of: dissolving platinum with aqua regia; removing nitre and acid; adding potassium chloride; filtering to obtain potassium chloroplatinate precipitate; adding reductant solution; jointly processing by utilizing 200mW / cm<2> cosine ultrasonic wave under 20 to 25kHz and 200mW / cm<2> variable frequency ultrasonic wave under 35 to 40kHz, and continuously stirring at the same time, thus obtaining potassium chloroplatinite solution. According to the preparation method of the potassium chloroplatinite, the specific ultrasonic cavitation effect is utilized to promote the reaction process of reducing potassium chloroplatinate through potassium formate, thus the reaction time is shortened, the reaction is complete, and the yield of potassium chloroplatinite is increased.

Description

technical field [0001] The invention belongs to the field of inorganic compound synthesis, and in particular relates to a method for efficiently preparing potassium chloroplatinite under ultrasonic conditions. Background technique [0002] Cancer is currently one of the major diseases that seriously affect human health and threaten human life; together with cardiovascular and cerebrovascular diseases and accidents, it constitutes the three major causes of death in the world today. Therefore, all countries regard conquering cancer as a top priority, and research on anticancer drugs has become a hot spot in drug development. [0003] In 1969, Barnett Rosenberg accidentally discovered that cisplatin can inhibit cell proliferation, which aroused people's attention to the anti-tumor effect and mechanism of metal complexes. Nowadays, platinum-based antineoplastic drugs are widely used in the clinical treatment of tumors, and have a significant effect on a variety of tumors, and h...
