Patent NL-2030020-A (NL)
Title: Detection digestion tube and pretreatment method for heavy metal in batch soil
Inventor: YONGJIAN CHEN
IPC: G01N1/44
Filed: 2021-12-03
Abstract: The present disclosure discloses a detection digestion tube and a pretreatment method for a heavy metal in batch soil. In the digestion tube of the present disclosure, an opening of a tube body is covered with a tube cover, and an eXhaust hole in a tube cover facilitates the eXhaust of acid mist during digestion. When the air pressure in the tube body is too high, the air pressure pushes open the edge of the tube cover, the interior of the tube body is communicated with the outside, and the air pressure in the tube body returns to standard atmospheric pressure quickly. The pretreatment method of the present disclosure comprises the following steps: (1) weighing a soil sample, placing the soil sample in the digestion tube, adding nitric acid-perchloric acid mixed acid and hydrofluoric acid at one time, and covering with the digestion tube cover, (2) first, placing the digestion tube in a graphite digestion instrument to perform programmed temperature control digestion, then maintaining a final digestion temperature, opening the digestion tube cover, adding water, and covering to continue stewing, and (3) turning off the graphite digestion instrument, taking the digestion tube out for cooling, flushing the digestion tube cover and enabling a flushing fluid to flow into the digestion tube, then making the content in the digestion tube in a constant volume, and diluting for ICP-MS detection. The time of the pretreatment method is controlled within 5 hours from the addition of the acids to the end of the digestion. The digestion process is controlled only by time and temperature, and whether the digestion is completed does not need to be determined manually, so the requirement on an operator is low. Only one time of manual intervention is needed during the digestion, so the possibility of pollution is reduced. The required acids are added at one time before the digestion, so there is no operational risk of adding an acid at a high temperature halfway.

Title: Oxidn. of reduced vat or sulphur dyes - with alkali-metal chlorite(s) in presence of chelating agents
IPC: D06P1/22
Filed: 1978-11-22
Abstract: Dyeings produced by the application of the reduced forms of vat or sulpur-dyes are oxidised by alkali metal chlorites, e.g. Na chloride in acid medium, to which chelating agents have been added. Oxidn. of vat or sulphur dyes is usually carried out with alkali peroxides, oxygenated water or alkali dichromates. The first two tend to lead to 'suroxidn.' with certain sulphur dyes, and dichromates often cau se dulling of shades, as well as causing pollution. No such problems arises with chlorites but they must normally be applied at a relatively alkaline pH and high temp. than normal (>80 degrees C). It has now be found that they can be applied at acid pH if chelating agents are added to the bath, they do not affect the tinctorial character of the oxidised dyeings.
