Method for preparing sodium chlorate from industrial salt

Abstract: The invention discloses a method for preparing sodium chlorate from industrial salt. The method comprises the following steps of: (1) mixing industrial salt with water to prepare industrial salt water, filtering and purifying the industrial salt water, putting industrial salt water into an electrolytic cell after processing to perform electrolysis, thereby obtaining a sodium chlorate solution; performing vacuum low-temperature continuous evaporation to obtain a mixture of sodium chlorate crystal and a sodium chlorate mother solution, and separating the sodium chlorate crystal from the sodium chlorate mother solution for the obtained mixture, adding anti-blocking substances in a separating process, feeding the separated-out sodium chlorate mother solution into a treatment slot for treatingsulfate radicals, adding a flocculating agent to stand after treatment, and performing dehydration separation after standing. A proportion of calcium chloride to barium chloride is controlled, so thathigh yield within unit time in a production and electrolysis process for sodium chlorate is realized, and power consumption of unit yield is reduced; and meanwhile, the prepared chlorate has a very good anti-blocking effect.

Preparation method and applications of polymerization ferric chloride

Abstract: The invention discloses a preparation method of polymerization ferric chloride. The preparation method comprises following steps: excess iron blocks are added into A hydrochloric acid so as to obtaina ferrous chloride solution, a sodium chlorate solution is added with stirring, B hydrochloric acid is added, an obtained mixture is stored at room temperature for aging, sodium phosphate is added asa stabilizing agent so as to obtain polymerization ferric chloride. The beneficial effects are that: the preparation method is simple; and the obtained polymerization ferric chloride can be used for effective processing of sewage.

Other Herbicides and Mechanisms

Abstract: The total herbicide sodium chlorate may be reduced by the enzyme nitrate reductase to yield the highly reactive and acutely phytotoxic chlorite ion (CIO 2 - ): Open image in new window This has been shown to be true for Chlorella [1–3], Chlamydomonas [3], and tomato [4]. The same obviously applies to other higher plants which have been used as starting material for the selection of resistant lines, as discussed below. However, CIO 3 does not act as an inducer of nitrate reductase. The alternative reduction of nitrate or clorate by nitrate reductase is a competitive process. The km for chlorate has been estimated as 2.3 mM for Chlamydomonas reinhardii, 1.2 mM for Chlorella vulgaris, 3.9 mM for Chlorella pyrenoidosa, and 4 mM for tomato. The reduction product chlorite leads to the rapid inactivation of nitrate reductase and possibly other enzymes in the vicinity and may thereby display its phytotoxic action.

Environmental-protection type coal-saving surface-removing dust-reducing emulsion and its preparing method

Abstract: This invention relates to an environmental protection coal-saved sulphur-remove and dust-reducing emulsion. Taking the weight percentage as one unit, 25%-75% weight portion of distilled water is added into a reaction kettle to be mixed and heated to 60-80deg.C then 0.1-1.5% weight portion of a malcate and 0.1~5.5% of light hydrocarbon are added and mixed at high speed for 15-35min to keep the temperature, then 0.1-0.5% portion of sodium tetraborate, 0.1~20% of sodium nitrate, 0.1~5% of sodium chlorate, 0.1~2.5% of sodium dioxide, 0.1~5% heavy sodium chromate and 0.1~3.5% ammonium perchlorate are added into the kettle to carry out chemical reaction and mix for 15-30min then enters into a high speed jet crushing machine to cut them repeatedly for 3-5times.
