The free energy change (Î´G 0) for the adsorption process was found to be â12.60 kJ/mol. The results indicated that the biomass of Ulothrix zonata is a suitable biosorbent for both the removal and recovery of heavy metals from wastewater.hen, a given amount of inactivated dried U. zonata was suspended in double distilled water by homogenizing for 45 min in a Waring blender. An algal suspension was prepared in solidâliquid ratio of 10 g alg/l solution and used by diluting. The surface area of the biosorbent was determined to be 1.1 m 2 /g (BET-N 2).
A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. The most common application of ion-selective glass electrodes is for the measurement of pH. The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions. Glass electrodes play an important part in the instrumentation for chemical analysis and physico-chemical studies.
What Is an Electrode? An electrode conducts electricity in an electric circuit. It can come in the form of a plate, rod or wire and is made of metals like copper, lead, zinc or silver. Some electrodes, though are made of non-metallic substances like carbon. Electrodes used in electrochemical cells are either anodes or cathodes, depending on the electrical charge. The anode is the positive electrode, and it is through this that the electrical current passes out of the cell and triggers oxidation.
