Plumbum ions

I cm of 0.05 N NaOH, and diluted with distilled water to 10 cm. Six erlenmeyers of corncobs hemicelluloses solution titrated with a solution of 3 mg/cm cadmium ion. However, the other six erlenmeyers of hemicelluloses solution titrated with a solution 10 mg/cm plumbum ions. The end point of the titration was Indicated by the formation of a white precipitate [3,33]. 

The titration results of corn cobs hemicellulose bond between the metal ions cadmium and plumbum ions are shown in Tables 8.2 and 8.3. Based on Table 8.2, it appears that 100 mg of corn cobs hemicellulose was bond cadmium at (46.88 0.5094] mg. According to Table 8.3, it appears that 100 mg of corn cobs hemicellulose was bond plumbum at (67.82 0.4280] mg. This implies that the cadmium ions and plumbum ions can release sodium from hemicelluloses [33, 34]. Because based on their group in the periodic system, sodium was contained in class lA and had a low electronegativity compared to cadmium ions in group... 

This is reinforced by laws developed by [38], the law of the hard soft acid base, which states that the bonding that occurs in hemicellulose also occurs at hydroxyl groups contained in the carboxylate groups and hydroxyl corn cobs hemicellulose. Although the reaction between sodium—a strong acid—and a hydroxyl compound of hemicellulose—a strong base—can be replaced by other cations, there are soft acids such as cadmium ions and borderline acids such as plumbum ions [20], This indicates that the titration performed in the alkaline pH of the hemicellulose can bind cadmium with endpoint white precipitation of cadmium hydroxide or endpoint white precipitation plumbum hydroxide from plumbum [3],... 

From Figs. 8.3a and 8.3b, it can be seen that there are a shifting in the location of the vibration of the corn cob hemicellulose prior to reaction with cadmium and plumbum. This shows that the inclusion of cadmium and plumbum ions on corncob hemicellulose, will change the location of groups vibrations contained in corn cob hemicellulose. In the FTIR vibration, hydroxyl vibration of corn cobs hemicellulose in the... 

Tables 8.4 and 8.5 show that there Is the influence of the type of chelating agent and the weight of the chelating agent applied. Compared to hemicellulose, 100 mg pectin has the lowest binding capacity of 21.10 1.08 mg of plumbum ion or 52.75%. However, 200 and 300 mg pectin will give a greater ability in binding capacity of 32.48 0.71 mg or 81.20% and 37.39 0.22 mg or 93.47% of plumbum ion, respectively, which shows that the corn cob hemicellulose has a greater chelating effect than pectin [34].

Absorption characteristics between hemicelluloses and pectin are different where hemicelluloses react with plumbum ions. This suggests that the hydroxyl group of the hemicellulose causes attraction of plumbum ions present in solution. Thus,... 

Figure 8.5 Charts comparison of hemiceiiuiose and pectin bound to plumbum ions.

Rabbits were given 100 meg of cadmium ions and 100 meg of plumbum ions orally every 2 days for 2 weeks and then as much as 3 cm of it was drawn. The total of 1 cm was used to determine the levels of cadmium and plumbum in the blood. Furthermore, it was given 10 mg corn cobs hemicellulose together with 100 meg of cadmium ions and 100 meg of plumbum ions every 2 days. After 2 weeks, as much as 3 cm of blood was drawn. It is used to test the results of the implementation of this by checking the cadmium and plumbum levels In blood samples. It was held for 10 weeks [34]. 

Respect for Cadmium (Cd) Ion and Plumbum (Pb) Ions with Titrimetric in the pH Bases... 

The chelating ability of corn cobs hemicellulose, and pectin toward cadmium ion and plumbum is shown in Tables 8.4 and 8.5. The administration of chelating agent to bind distinct cadmium and plumbum in the pH 2 gives different results. From Tables 8.4 and 8.5, it can be seen that there is an influence of the type and weight of chelating agent applied. However, in contrast to pectin, with the addition of pectin, the concentration will also increase properly the strap to cadmium ions [34],...
