In order to see the effects of salt variation on the electrical and mechanical properties of the structural supercapacitor, three salts (lithium perchlorate, potassium perchlorate, and zinc chloride) were used.
(19.) MSDS: Potassium Perchlorate; MSDS: Magnesium (Powder).
Because previously reported chromatographic conditions (8,15,16) could not be applied directly to CSF analysis, we evaluated the optimum conditions by studying the effects of different salts, such as lithium, sodium, and potassium phosphate buffers; amines such as triethylamine (TEA), trimethylamine, morpholine and guanidine thiocyanate; and the chaotropic agent potassium perchlorate in different concentrations in mobile phase A.
Fireworks, flares and other so-called "pyrotechnics" traditionally have included potassium perchlorate as the oxidizer, a material that provides the oxygen that fireworks need to burn.
In the 1960s, potassium perchlorate was used to treat patients with Graves disease.
Perchlorate is the dissociated anion of perchlorate salts such as potassium perchlorate, sodium perchlorate, and ammonium perchlorate and is extremely water soluble and environmentally stable.
Potassium perchlorate (500 mg/L) was found to inhibit fin formation and skin pigment differentiation in early life stages of zebrafish, Danio rerio (Brown 1997), and in a study of adult zebrafish a high level of ammonium perchlorate (18 mg/L) resulted in thyroid hypertrophy, hyperplasia, and colloid depletion after 8 weeks of exposure (Patino et al.
Subgroups of these animals were treated for 10 days with a low iodine diet plus 1% potassium perchlorate in their drinking water.
Treatment of thyrotoxicosis (including Graves' disease) with 600-2,000 mg potassium perchlorate (430-1,400 mg perchlorate) daily for periods of several months or longer was once common practice, particularly in Europe (7,8).
