Details

The Hach Ammonia ISE Analysis Package includes the Hach Ammonia Electrode which measures ammonia gas or ammonium ions in aqueous solutions that have been converted to gas by the addition of a strong base. The electrode is a complete electrochemical cell consisting of a glass pH electrode and a reference electrode.

The gas-permeable membrane separates the sample from a thin layer of electrolyte that is pressed between the pH bulb and the membrane. At high pH, ammonium is converted to ammonia gas. The gas diffuses through the membrane and causes a pH change in the thin layer of electrolyte. The potential across the pH glass changes as a result of the pH change and the electrode measures the change in potential. The measured pH change is proportional to the ammonia concentration in the solution.

The ammonia electrode will measure ammonia gas or ammonium ion (converted to gas by strong base) in a variety of aqueous samples. Applications include water, wastewater, boiler feedwaters, fertilizers, biological samples, fish tanks, and more.

ROVs Sparking Compassion and Curiosity at the Shedd Aquarium

This summer, the team from the Shedd Aquarium in Chicago began pilot programs designed to reach local communities in a new way. Specifically, they ran excursions on both Lake Michigan and the Chicago River using ROVs equipped with underwater cameras and other tools to introduce more land-dwellers to what lies beneath the water. Shedd Aquarium Learning Programs Manager Sadie Norwick and Communications and Public Relations Coordinator Kayley Ciocci spoke to EM about the Shedd's innovative ROV programming for the public. Inspiring conservation with technology Although the pilot programs using the ROVs were new in 2018, the Shedd team is no stranger to using ROVs to educate the public.

TMACOG Program Empowers Teachers to Bring Water Quality to Classrooms

This summer, teachers across northwest Ohio took the time to learn about water quality in Waterville at Farnsworth Metropark. The teachers were training in the Maumee River for the Student Watershed Watch (SWW) program , run by TMACOG. “TMACOG is the Toledo Metropolitan Area Council of Governments, Sara Guiher, a water quality planner and SWW coordinator for TMACOG, explains to EM. “We're a regional planning organization and we work with local governments on issues related to stormwater, wastewater, drinking water, and watersheds. This program started in 1989, and it’s one of our longest running programs.” The program was designed to foster stewardship through the sampling process.

Sunscreen Chemicals in Water Can Harm Zebrafish Embryo Development

If you've ever sat at the beach or on the shore of a lake reapplying your sunscreen and wondered what happens to that sunscreen as it washes off in the water, you're in good company. A team of researchers has been investigating how sunscreen chemicals affect marine wildlife, and their recent paper indicates that ultraviolet (UV) filters from sunscreen and other personal care products can affect zebrafish embryo development. UV filters in the water Dr. Adela Jing Li's group at Hong Kong Baptist University has been studying UV filters for several years.
