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.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).hen the cell is being charged, the anode becomes the positive (+) and the cathode the negative (â) electrode. This is also the case in an electrolytic cell. When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.
