This European Standard specifies the determination of S, Cl, F and Br in solid recovered fuels of various origin and composition after combustion in oxygen atmosphere. This method is applicable for concentrations over 0,025 g/kg, depending on the element and on the determination technique. In the case of fluorine this method is applicable for concentration over 0,015 g/kg. Insoluble halides and sulphate present in the original sample or produced during the combustion step are not completely determined by these methods. This European Standard provides recommendations concerning standardised methods for determination of halides and sulphate in the solution obtained after combustion.
7、无卤素(F.Cl.Br.I)检测标准测试卤素(F.Cl.Br.I)检测,氯+溴含量不超过1500PPM,测试方法EN14582 method B六个工作日出检测报告无卤要求:溴、氯含量分别小于 900ppm ,(溴+氯)小于 1500ppm 。...
16.氯溴碘和磷酸根,加酸再加硝酸银:“氯溴碘”在此指CI-、Br-、I-。这两句的意思是说Cl-、Br-、I-和PO43-的鉴别方法是分别加稀硝酸然后再加硝酸银。有白色沉淀生成者则是Cl-、有淡黄色沉淀生成者则是Br-、有黄色沉淀生成者I-、无沉淀生成者为PO43-(这是因为PO43-和Ag+也能生成类似AgI的黄色沉淀Ag3PO4,但是它可溶解于稀硝酸中)。...
6.氟氯溴碘四元素,颜色渐深气变固:意思是说这四种元素的单质的颜色是逐渐变深的,状态是由气态变到固态(氟是淡黄绿色气体、氯是黄绿色气体、溴是红棕色液体、碘是紫黑色固体)。7.半径密度渐递增,溶点沸点亦上升:意思是说这四种元素的的原子半径、离子半径、及其单质的密度是逐渐增大的,熔点和沸点也逐渐升高。...
