[Chromium Speciation: Speciate different components over x-y]

Hi,

I am trying to plot different Cr species over x-y diagram. I would loke to plot pH on the x-axis and Total Chromium concentration on the y-axis. From the analysis, I have Cr (Total)= 14 mg/l, Cr+++= 8.5 mg/l, and Cr++++++= 5.5 mg/l and pH= 7.2. Could you please help me in plotting these data?

 

Thanks,

Ari

[Multiple analysis]

Dear Ari:

 

Have a look at the Appendix entitled 'Multiple Analyses' in the GWB version 7 Reference Manual.

 

I hope that helps,

I have looked at multiple analysis appendix but it does not help. I don't want to calculate anything right now. I just want to load data from multiple sites. Will it be possible for you to run me through this? I can provide the Spreadsheet that I am trying to incorporate in GWB.

 

Thanks,

Ari

[Multiple analysis]

How can I simply load multiple chemical analysis data (hundreds of data, from different sites and different time periods) in a place so that I can run them in Spece8. I am new and trying to do this in an efficient way. I know version 8 came up with an option for loading multiple data in the GSS but I am using essential (7.0) version. Please help.

 

Thanks in advance,

Ari

[SpecE8 Error]

Hi everyone,

I am trying to run SpecE8 and after assigning the aqueous species when I hit the go button I am getting the following error message:

 

"Could not open SpecE8_output.txt file.

(Do you have write permission in this directory?)"

 

Could you please help me in this regard?

 

 

 

I also tried to put Cr++++++ as an aqueous species, but instead I have the only option of assigning Cr+++. Any suggestion?

 

 

Thanks,

Ari
