A Novel Lab-on-Chip Spectrophotometric pH Sensor for …

(1σ) Δt = t − t m (eq 2) was −1.1 (0.5) °C(n = 1693). The combination of pH T,m with TA or DIC is the most rigorous way to compute the temperature eﬀect for site-speciﬁc environmental conditions,46 especially for large temperature adjustments. The use of the linear temperature correction46 for small temperature adjustment here is an expedient …

Carbon Dioxide, Alkalinity and pH

• The pH of seawater varies only between about 7.5 and 8.4 (i.e., slightly alkaline) • Over geological time, pH is thought to be controlled by water/mineral equilibria • Over shorter time scales (104 to 105 yrs) the CO 2 system (and its shifting equilibria) regulates seawater pH CO 2(aq) + H 2O ↔ HCO 3-+ H+ Seawater pH – T and P Effects

A popular approach to mathematical modeling of the combined effect of temperature, pH, water activity, oxygen tension, and the concentration of salts, sugars, alcohol, and/or antimicrobials on microbial growth rate is known as the gamma hypothesis. It is based on the notion that the growth rate, however defined, can be expressed as a …

Effect of drought stress or soil pH on cesium accumulation

Radio-cesium (Cs) decontamination efficiency by plants is supposedly affected by environmental conditions. To elucidate the factors influencing the unstable 137Cs-decontamination efficiency, we first examined the influence of drought or soil pH on Cs accumulation using cesium-133 (133Cs) using Napier grass (Pennisetum purpureum …

Performance of autonomous pH sensors is evaluated by comparing in situ data to independent bench-top measurements of pH and to co-located pH, O 2, and p CO 2 sensors. While the best practice is always to deploy a properly calibrated sensor, the lengthy time period required for sensor conditioning and calibration often results in sensor …
