Treasure the ammonium persulfate of science and technology expansion project construction

Treasure sinochem new dispatch of shaanxi treasure chemical technology co., LTD. Ammonium persulfate expansion project has started. The company in early 2012 by ammonium persulfate products in shaanxi province famous brand products, market share rapidly increased by 20%, 10000 tons of annual production capacity has been originally does not meet the market demand. To this end, the company raised 9 million yuan, expanding production line 2, an annual output of 3000 tons of increases. The expansion will also be on the production process of evaporation crystallization system technical renovation, will further enhance the production efficiency and quality of ammonium persulfate.

Ultraviolet spectrophotometric method of alkaline potassium persulfate

Abstract: using the alkaline potassium persulfate digestion ultraviolet spectrophotometric method for determination of total nitrogen in water, examining the factors affect the total nitrogen in the experimental results. Experimental results showed that potassium persulfate reagent selection, configuration of the alkaline potassium persulfate reagent, digestion time, digestion temperature and pressure control, the control of hydrochloric acid to join after the reaction time and so on all can influence the outcome of the determination of total nitrogen.
