I have a problem with such a sentence:
Today is used not only lime, soda ash and sodium sulfide but also trithiocarbonates.
I am not certain whether all elements needed are included.
Will the following version be ok?
Today, it is used not only lime, soda ash and sodium sulfide but also trithiocarbonates.
Maybe this version is better?
Today, there is used not only lime, soda ash and sodium sulfide but also trithiocarbonates.
From comments: But the main thing is that I want this sentence to be like a suggestion. I want to express that currently there are more widely used substances (except from these mentioned) for this specific purpose.
I am ready to see your suggestions.
