In most natural waters the molecular HCN form predominates. In solutions of metal cyanides. the CN group may also be present as a complex of varying stability. Cyanides are extensively used for extraction of silver\/gold ores. metal-cleaning and electroplating baths. coke ovens and other chemical processes. There are mainly two chemical treatments to remove cyanides from waste-waters: one is chlorination and the other is the alkaline method.\u003c\/p\u003e\n\u003cp\u003eCyanides react with the pyridine-pyrazolone reagent to form a blue complex in neutral buffered solution. The absorbance of this colored product is proportional to the concentration of cyanide present in the aqueous sample.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOrder Information:\u003c\/strong\u003e\u003cbr\u003e HI 3855 test kit comes with 17 g cyanide reagent A. 100 packets cyanide reagent B. 100 packets cyanide reagent C. checker disc. glass vials with caps. 3 mL plastic pipette and spoon.\u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003eProduct Manuals\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cimg src=\"http:\/\/www.hannainst.com\/usa\/images\/icon-pdf.gif\" alt=\"\" width=\"20\" height=\"22\" align=\"absmiddle\" border=\"0\"\u003e  Manual: \u003ca title=\"Download Product Manual\" href=\"http:\/\/www.hannainst.com\/manuals\/manHI_3855.pdf\" target=\"_blank\"\u003eDownload\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification :\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003eChecker Disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e0.00-0.30 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmallest Increment\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e0.01 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemical Method\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003ePyride-pyrazolone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Tests\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e580 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":4857187717,"sku":"HI3855","price":278.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/0956\/products\/31gluhj8kul__sl500_aa300_51e079d42298c_2015.jpeg?v=1465536753","url":"https:\/\/acornsci.co.nz\/products\/hi3855","provider":"Acorn Scientific","version":"1.0","type":"link"}
