When you want to open a modal popup from Content Editor ribbon, it should be done using a Sitecore Command.

On your Command class itself, you can find the context item (Selected item), and pass it's Id in querystring of popup.

In the Execute() method of your Command class, your code will look like below.

    public override void Execute(CommandContext context)
    {
        if (context.Items.Length == 1)
        {
            // Get currently selected item in Content Editor tree
            Item currentItem = context.Items[0];

            // to read passed parameters, use context.Parameters["id"];

            // Continue your code for popup    

        }
    }
