初衷养了海缸三五年了，经历了三五次翻缸，一将功成万骨枯，虽说不敢说养的多好，但多少从失败之母那里学到了不少东西，于是乎不满足于换水，开始考虑添加一些微量元素。逛了一圈成品，发现好贵啊，不符合张大妈的大侄子的风格，自己动手，丰衣足食。
筹备
卡莫尔买了几个蠕动泵，一个十块钱多一点点。卡莫尔是大牌子，很专业的。这个泵根据电压调整转速，所以适配合适的电源后要测量一下实际一分钟滴多少毫升。
除了泵有了，还要配上软管等配件，还有装溶液的盒子。
装试剂的瓶子当然尽量要避光，然后为了摆放整齐选方形的，尽量选大容量的，这是我能找到的最大容量的了
基础的东西有了，现在需要一个控制程序。有两种方案，一种是易微联主板，最多控制6路，可连米家可远程。再多的话只找到了一个6路的，但是只能热点链接的情况下用wx小程序控制。没有找到很完美的方案。我要滴定6个元素加上进水排水，所以说选择了6路的。
然后先这样，再那样，然后这样，就组装好啦

郎郭性2287什么是返滴法 -
毕逄胡13860465161 ______ 返滴定法(剩余量滴定,俗称回滴):当反应较慢或反应物是固体时,加入符合计量关系的滴定剂,反应常常不能立即完成.此时可以先加入一定量过量的滴定剂A,使反应加速.等反应完成后,再用另一种标准溶液B滴定剩余的滴定剂A.这种...

毕逄胡13860465161 ______ 典型的滴定方式有直接滴定、反滴定、间接滴定和置换滴定四种. 1.直接滴定法 凡是能满足上述要求的反应都可以应用于直接滴定法中,即用标准溶液直接滴定被测物质.直接滴定法是滴定分析中最常用和最基本的滴定方法. 例如,以HCI滴定氢氧...
郎郭性2287滴定分析的特点有哪些 -
毕逄胡13860465161 ______ 滴定分析法,又叫容量分析法,将已知准确浓度的标准溶液,滴加到被测溶液中(或者将被测溶液滴加到标准溶液中),直到所加的标准溶液与被测物质按化学计量关系定量反应为止,然后测量标准溶液消耗的体积,根据标准溶液的浓度和所消...
郎郭性2287配位滴定中,什么情况下不能用直接滴定的方式 -
毕逄胡13860465161 ______ 在配位滴定中,如果标准滴定溶液和被测离子的反应速度很慢,或者没有合适的指示剂,都不易采用直接滴定的方式,采用返滴定法、置换滴定法和间接滴定法等其他滴定方式.
