在用碘量法测铜精矿中铜含量时,无论试样中含碳量高低,对试样处理上都应在处理试样时适量加入H2SO4和HClO4冒烟蒸干,以提高分析结果的准确性。
在用碘量法測銅精礦中銅含量時,無論試樣中含碳量高低,對試樣處理上都應在處理試樣時適量加入H2SO4和HClO4冒煙蒸榦,以提高分析結果的準確性。
재용전량법측동정광중동함량시,무론시양중함탄량고저,대시양처리상도응재처리시양시괄량가입H2SO4화HClO4모연증간,이제고분석결과적준학성。
When we determine copper in copper concentrates using iodometry method we all must add sulphuric acid and perchloric acid no matter how much carbon is.So when the water of the solution is exhausted by evaporation with smoking we can improving accuracy of analytical results.
