Is There Any Way To "Unroot" An Android Device?

I'm giving a Samsung Galaxy S4 phone to my friend for her daughter to use via Wifi only. There is no SIM card or provider for the phone,but it is rooted.
Is there a way to "unroot" the phone???
Chrome is not working, along with a few of the account settings.
Any helpful information would be much appreciated!!emoji23.png
