Hi dear, Secure Folder will work only on recent samsung devices. It will not work on your device if the device is older than 3 years.
There is an app which samsung introduced before Secure Folder. It's called My Knox. It was available when I bought Note 4. Now samsung has withdrawn this app from playstore. Still you can download that app from apk mirror or other websites.. I will include a link to the apk so that you can download it. Try it, I am not sure whether it will be supported in your device, but give it a try.
