    摘要: A system and method for the detection and removal of copper from wastewater streams from semiconductor or printed circuit board manufacturing is described and claimed. The detection system and method involve the addition of a reagent that reacts with copper to quench the fluorophore present, with the decrease in fluorescence being detected by a fluorometer. The reduction of fluorescence is then used to calculate the amount of copper present in the form of Cu+2 ion in the wastewater. The removal system and method involve either the addition of a polymer that reacts with copper to form an insoluble precipitate with said precipitate then being removed by using any technique commonly known in the art; or the use of an ion exchange column to remove the copper from the wastewater stream.

    摘要: The invention is a method of monitoring for the presence of certain constituents of food processing streams by measurement of fluorescence. The constituent monitored can be a fluorescing impurity of a food product, or the food product itself if such naturally fluoresces. Moreover, losses of the constituent to be monitored may be determined by concurrent measurement of fluorescence of a fluorescent material added to the food process stream. The method is applicable to the following food processing streams among others: meat, vegetable oil, sugar beet, sugar cane, grain, poultry, fruit and soybean processing streams. Upon determination of a variation of the fluorescing constituent to be measured, the food process can be adjusted accordingly.

    摘要: New zinc stabilizing polymers containing at least 5 mole percent of a monomer represented by the structure: ##STR1## wherein: R is independently, at each occurrence, chosen from H and lower (C.sub.1 -C.sub.4) alkyl groups;R' is a hydrocarbonaceous bridging group containing from 1-12 carbon atoms;X is chosen from --SO.sub.3 M, --OH, --COOM groups or mixtures thereof,M is hydrogen or some other cation species; andn ranges from 1-10,are described. Also, the use of these polymers in combination with zinc salts, and in further combination with phosphate salts, to inhibit corrosion of iron containing metals, and other metals, when these metals are exposed to industrial waters is demonstrated. Deposit control or scale inhibition on these metals exposed to industrial waters is also observed.
