The invention discloses a method for removing cells from a human amnion. The method is characterized by comprising the following steps of: obtaining a clean semitransparent amnion, rinsing the semitransparent amnion by using a PBS (Phosphate Buffer Solution), soaking the semitransparent amnion in a comprehensive PBS liquid, shocking, rinsing the amnion by using the PBS after the amnion is taken out, successively soaking the amnion in steapsin / PBS liquid and deoxyribonuclease / PBS liquid for treatment, rinsing the amnion by using double-antibody / PBS liquid, taking out the decellularized amnion and putting the decellularized amnion in the PBS for preservation and standby. The method has the advantages that the cells are removed from the amnion in a manner that a surfactant is combined with steapsin and deoxyribonuclease, the cells can be prompted to be completely and efficiently removed from the amnion due to the combined use of the steapsin and the deoxyribonuclease, and meanwhile, the extracellular matrix is reserved to the maximum and is enabled to be free from damage.

The invention relates to a phosphorus removing agent containing inorganic mineral and an application method thereof. The phosphorus removing agent contains 50-75% of an aluminium-containing compound, 15-30% of an inorganic mineral adsorbent and 10-20% of an iron-containing compound, and also can be compounded with a B component. By the use of the phosphorus removing agent, inorganic phosphorus and organic phosphorus in wastewater are removed effectively. By the addition of the inorganic mineral adsorbent, phosphates are fully adsorbed, and the inorganic mineral adsorbent can be combined with iron hydroxide and dried aluminium hydroxide gel generated during the reaction. Thus, more phosphates and pollutants in water can be adsorbed to form larger floc, and settling and flocculation processes are accelerated. Through the synergistic effect of substances, a better phosphorus removing effect is achieved. The phosphorus removing agent has a very good effect of processing orthophosphate, polyphosphates and organic phosphorus and especially has a function of efficiently removing organic phosphorus. In addition, the application method of the phosphorus removing agent is simple.

A method of dried bromide gases belongs to the field of inorganic chemical and hydrogen gaseous purification technology.This method of dried bromide gases allows the hydrogen gases containing moisture to enter the drying tower of the filler from the bottom, and connect the liquid inorganic bromide, triglycetic phosphorus and hydrogen bromide from the top of the drying tower of the fillerThe gas is in the inverse flow of the drying tower in the drying tower. The two -stage series of filler drying tower is dried. After passing the dehomato, the water content is lower than 20 ppm dry bromide gases. At the same timeEssenceTrilyarized phosphorus liquids can be used circularly, but after the concentration is less than 80%, vacuum distillation can be used to recycle and use it.This method is more efficient than the current method. The dehydration efficiency is higher. The water content of hydrogenation can be less than 20PPM. It is suitable for the case where the hydrogen gaseous pressure is relatively small in the production process. It is especially suitable for bromine bromine bromine in hydrogen.The removal of water in hydrogen gases.
