What is the common way to remove all types of heavy metals from tap water?
is it possible to remove all heavy metals from tap water if yes how this can be done ? is there a common technique to remove all or most heavy metals in tap water are applied now ? thanks for all answers

The reverse osmosis unit. This filter installs under the sink, and its installation requires the arrival of a professional. Even more efficient than tap filters, the osmosis system circulates the water through several purification steps. First, the ceramic pre-filter removes dust, rust. Then, a filter composed of DFK (degration fluxion kinetic, which is a zinc-copper alloy) filters heavy metals. A water filter can be fitted to the faucet without the need for special tools. It contains a charcoal cartridge that filters an average of 1,200 liters and needs to be changed every three months or so. It is a particularly recommended system for removing bad odors due to chlorine, but also pesticides, nitrates and heavy metals.
With my best regards

Methods for removal of some trace amounts of toxic metals include distillation, ion exchange, reverse osmosis, and activated carbon filtration.

What shoud I do for preservation of ion chromatography?
- Alireza Valipour
Hello everybody. Our instrument (i.e., ion chromatography) must stop working for more than 4 months because of some maintenance. My question is, during 4 months or more, does it need anything done for preservation? However, we have already removed the columns and are storing them in the refrigerator.
Thanks a lot
Data accuracy for ion chromatography?
- Nazanin Hamnabard
Hi every body
I am using ion chromatography for analysis of water samples. these samples are surface water.
I got the concentration of anion ( NO3, Cl, SO4) and Cations ( Na, Ca, Mg, K).
Then I Did titration for CO3 and HCO3 .
Summation of total Anions and Cations is not equal and I got error[ ( Sum anions-Sum cations/ sum anions +sum cations) *100 ] more than 2% even 5%.
my question is about this error. Is this error is correct? I mean this error can be one solution for Data accuracy from chromatography. If not correct, how can I confirmation of data? from chromatography. If not correct, how can I confirmation of data?

How to determine the true concentration of a water sample based on ion chromatography and spectrophotometry results?
- Ariel Greenblat
I have >200 water samples that I have analyzed for nitrate-N concentrations using a spectrophotometer (spec) (HACH DR 2800). I selected 23 samples to be analyzed by ion chromatography (IC) at a certified lab to ensure the accuracy of my results. I am confident the IC results are more accurate than my spec results, so I would like to know if there is something I can do to "transform" or "adjust" all my samples based on the relationship observed by the 2 methods for the 23 samples.
In short, how can I determine the relationship between the 2 methods (if one even exists)?
I have attached a spreadsheet with the results from both methods and sample IDs.

How to remove chloride when running Ion chromatography?
- Wenxin Bai
Hello everyone, I am running Ion chromatography (IC) recently for the detection of sulfate, nitrate, lactate, and acetate. However, the salt in my medium is quite high which shows a huge peak when I run IC of my samples (picture attached), I wondered if there are some methods for removing Chloride without disturbing sulfate and nitrate? I've tried the PD10-desalting column, which could remove chloride but at the same time remove all other salts to a different extent.
