CHANGES IN INORGANIC PHOSPHATE CONCENTRATION DURING WATER SAMPLE STORAGE
Abstract:
In this paper the adsorption of inorganic phosphate by polyethylene bottles, samples storage condition and the pre-treatment of samples and bottles have been discussed. Experiments should that the concentration of phosphate does not change within 24 h, of distilled water solution containing phosphate and phosphote was quickly adsorbed on bottles. The phosphate in seawater samples would be lost very quickly. Therefore, in general, the polyethylene bottles should not be used for the storage of phosphate. The rate of changes of phosphate would go down by adding 0.3%v/v chloroform into the samples. The changes in phosphate concentration were less in the 62 days storage at -25t and the effect was still good for the samples with chloroform. Experiments also showed that the bottles treated with distilled water solution or seawater containing higher phosphate concentration could resist the decrease of the phosphate in samples.
