The invention discloses a manufacturing process of an antibacterial mask. The manufacturing process comprises the following steps: step 1, preparing an antibacterial layer; step 2, preparing an activated carbon fiber layer; and step 3, sewing a non-woven fabric layer, an activated carbon fiber layer, the antibacterial layer, the activated carbon fiber layer and a non-woven fabric layer which are stacked in sequence by using a hot melting edge-sewing technology to obtain a mask body, sewing the mask body and ear bands together, and arranging a plurality of nasal clamping strips at equal intervals in the upper opening edge sealing cloth roll to obtain the antibacterial mask. An auxiliary agent contains unsaturated double bonds, a fluorine-containing alkyl chain and a benzene ring, the unsaturated double bonds in the auxiliary agent can be subjected to a polymerization reaction, and the introduction of the fluorine-containing alkyl chain and the benzene ring improves the high temperature resistance of an antibacterial agent. A modifier is a quaternary phosphonium salt monomer containing unsaturated double bonds and is grafted to the surface of cotton fibers under the action of an initiator ceric ammonium nitrate to endow the cotton fibers with an antibacterial property, and chitosan is added and can be matched with activated carbon to improve the antibacterial effect in the aspect of adsorbing fine particles.

The invention discloses a method for measuring the trace elements of aluminum, chromium, copper, manganese, nickel and silicon in pure iron. The method uses a purifying agent and comprises the steps of putting a sample in a plastic bottle, adding hydrochloric acid and nitric acid dropwise to dissolve, adding water to dilute until the net weight of a solution in the plastic bottle is 50.0 g, adopting a standard addition working curve series solution, subtracting the background on an inductive coupling plasma atomic emission spectrometer, measuring the content of an analysis element in a standard addition working curve sample, calculating the actual content of the analysis element in the working curve series solution, establishing a working curve without subtracting the background, and measuring the contents of the trace elements of aluminum, chromium, copper, manganese, nickel and silicon in the pure iron.

The present invention provides a weight for fishing, which is hard to cause hang and has non harmful effects to peripheral living beings even though being remained in undersea. A holder is made of rubber having elasticity, comprising a storage chamber (21) for storing a ferreous spindle (11) and a thread fixed part (23) for fixing fishing threads (1). The holder (12) has an opening (22) through which the spindle (11) is inserted and removed from the storage chamber (21). The holder (12) holds the spindle (11) in the storage chamber (21) by own elastic force. In addition, the holder (12) may discharge the spindle (11) outside the storage chamber (21) from the opening (22) when the holder is subjected to a force against the elastic force.
