用EDTA测定自来水中的钙镁离子的含量。用移液管移取适量水样与锥形瓶中，用盐酸溶液和氢氧化钠溶液将水样的酸度调整为pH≈7.0，滴加HCl溶液调节酸度，加热煮沸，冷却后分别加入三乙醇胺溶液掩蔽Fe3+、Al3+、硫化钠溶液掩蔽Cu2+、Zn2+等重属离子和盐酸羟胺溶液，摇动1-2min，测总硬度是加氨性缓冲溶液，加入g铬黑T指示剂，测钙硬度是加氢氧化钠，加钙指示剂，摇匀后用EDTA标准溶液滴定至溶液由酒红色突变为纯蓝色，即为终点。

请英语高手翻译一下啊！急需！
这些都是在线翻译，教授看了根本就没通过！
Abstract
Determination of water by EDTA of calcium and magnesium content. Pipet with adequate water will remove the bottle and the cone-shaped, with hydrochloric acid and sodium hydroxide solution to the acidity of water samples adjusted to pH ≈ 7.0, adjust acidity dropwise HCl solution, heated to boil, cooled respectively Triethanolamine masking solution Fe3 +, Al3 +, sodium sulfide masking solution Cu2 +, Zn2 + and other heavy ions and hydroxylamine hydrochloride is a solution, shake 1-2min, total hardness measurement of the increase of ammonia buffer solution, adding g Eriochrome Black T indicator, measuring calcium hardness is Add sodium hydroxide, calcium indicator, shaken after the titration with EDTA standard solution to the solution by the mutation of the red wine of pure blue, that is the end.
Key words: EDTA; Determination of calcium and magnesium;
