Описание
Причина отменыThis practice describes the proper procedure for preserving phytoplankton samples with either formaldehyde or Lugol’s solution

Formerly under the jurisdiction of Committee D19 on Water, this practice was withdrawn in May 2020. This standard was withdrawn without replacement due to its limited use by the industry.

Значение и использование

4.1 Formaldehyde solution can be used as a permanent preservative of algae. Lugol's solution can be used to preserve algae for up to one year. Lugol's is a more suitable preservative for delicate algae such as naked flagellates.
