Quantitative analysis of total solid of a river water using gravimetric method by paper tissue

The developed analytical method is necessary to obtain a method that is efficient, effective, simple, and fast. Total solid usually measures using a gravimetric method. This study aims to determine the total solid of a river water using paper tissue in a gravimetric method. The developed method was evaluated and resulted in significant value. The microscopic result revealed that solid trapped in the paper tissue. The total solid value is about 5.84 mg. the precision test results an acceptable value about 0.44%. This method ensures its efficiency, effectiveness, and practical technique.
